A man walks 2.6 miles east, then turns and walks 6.7 miles north. What is his resultant
vector from start to finish?
Answers
Answer:
Yes cause he walks 6.7 miles
The displacement vector of the man is equal to 17.41 miles in the Northeast direction.
What is displacement?The displacement of an object can be defined as the shortest distance between two points. The displacement can be described as a vector quantity because contains both direction and magnitude. The displacement can be positive (+ve), negative, or zero and can change with time.
The distance is the total path traveled and is a scalar quantity as it has only magnitude, and no direction. The distance is always positive (+ve), it can never be equal to zero.
Given, a man moves 2.6 miles along AB in the East and then 6.7 miles North along BC.
The displacement (AC) of the man can be calculated by using Pythagoras' theorem:
AC² = AB² + BC²
AC² = (2.6)² + (6.7)²
AC² = 6.76 +44.89
AC = 17.41 miles
Therefore, the displacement vector of the man is 17.41 miles.

For maximum benefit, you should exercise 5-7 times a week for 60 minutes and your heart rate should be between _____________ of your max heart rate.
Answers
Answer:
60 to 80%
Explanation:
For maximum benefit, the heart rates during exercise regimes should be between 60 to 80% of an individual's maximum heart rate.
The maximum heart rate varies from individuals to individuals and largely depends on age. It is calculated by subtracting one's age from 220. For example, a person that is 40 years old would have a maximum heart rate of;
220 - 40 = 180 beats per minute.
Such a person's heart rates during exercises should be between 108 and 144 beats per minute for maximum benefits.
In a typical golf swing the club is in contact with the ball for about 0.0010 s. If the .045 kg ball experiences a force of 4000 N, what is the final velocity of the golf ball?
Answers
Answer:
v = 88.89 [m/s]
Explanation:
To solve this problem we must use the principle of conservation of momentum which tells us that the initial momentum of a body plus the momentum added to that body will be equal to the final momentum of the body.
We must make up the following equation:
[tex]F*t = m*v[/tex]
where:
F = force applied = 4000 [N]
t = time = 0.001 [s]
m = mass = 0.045 [kg]
v = velocity [m/s]
[tex]4000*0.001=0.045*v\\v=88.89[m/s][/tex]
9. A soft drink distibutor drove west 11 km from Minnehaha to Nut Plains. She then turned around and drove back east for 209 km to Dover
What distance did the soft drink dibutor travel
Distance
Answers
Answer:
220km
Explanation:
Given parameters:
Distance traveled from Minnehaha to Nut Plains = 11km
Distance traveled to Dover = 209km
Unknown:
The distance the soft drink distributor traveled = ?
Solution:
To solve this problem, we must understand that distance is the total length of path covered in a journey.
So;
Distance = 209km + 11km = 220km
The soft drink distributor covered 220km

What is Charles's law of gas?According to Charles' law, assuming the pressure is constant, the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature. French physicist J.-A.-C. Charles initially proposed this empirical relationship.
1. When Susie puts the balloon in ice water, the temperature of the gas inside the balloon will decreases and according to Charles' law its volume also decreases. That's why, she will observe the contraction of the balloon.
2. When Susie puts the balloon in hot water, the temperature of the gas inside the balloon will increases and according to Charles' law its volume also increases. That's why, she will observe the expansion of the balloon.

What is included in the units of Velocity that make it different from speed?What is included in the units of Velocity that make it different from speed?
Answers
Answer:
Direction
Explanation:
Speed is a measure of the distance covered by a moving object relative to the time it takes. It is a scalar quantity and, hence, measured irrespective of the direction the object is moving.
Velocity, on the other hand, is the speed of a moving object in a particular direction. It is a vector quantity, meaning that the direction of the moving object is important.
Therefore, the difference in the unit of speed and velocity is direction. The direction must be included in the unit of velocity.

Juan y Pedro transportan una caja que pesa 120,00 Lb sobre una tabla uniforme de 12 pies de largo y peso de 44,5 Lb. El peso de 120 Lb está a 4,9 pies de Pedro. ¿Cuál es el módulo de la fuerza en Lb que debe ejercer Pedro por el extremo derecho de la tabla horizontal para sostener este peso?
Answers
Answer:
F = 93.25 lb
Explanation:
To solve this problem let's use the rotational equilibrium condition
Σ τ = 0
let's fix a reference system located at the end of the table, the position of Juan and assume the counterclockwise turns as positive
F_jhon 0 - w l / 2 - W (l-4.9) + F l = 0
F = w l / 2 + W (l -4.9) / l
where w is the weight of the table and W the weight of the box
let's calculate
F = (44.5 12/2 + 120 (12- 4.9)) / 12
F = 93.25 lb

Explanation:
To describe the position of a water fountain relative to where one is standing, the distance and direction to the water fountain must be known.
This quantity is known as the displacement.
Displacement is a vector quantity with both magnitude and direction. To specify the magnitude of a displacement, we use the length of path and in this case the height or sometimes the distance.

A 2.25kg solid sphere has a rotational inertia about its center
• of gravity of 1.52kg.m2. What is the radius of the sphere?
Answers
Answer:
r = 1.3m
Explanation:
The moment of inertia of a solid sphere can be expressed using the formula;
I = ⅖ mr²
Where;
I = moment (kgm²)
m = mass of the sphere (kg)
r = rotational radius of the sphere (m)
Based on the provided information in this question, I = 1.52 kgm², m = 2.25 kg, r = ?
1.52 = ⅖ × 2.25 × r²
1.52 = 0.4 × 2.25 × r²
1.52 = 0.9 × r²
1.52 = 0.9r²
r² = 1.52/0.9
r² = 1.688
r² = 1.69
r = √1.69
r = 1.3m
An object of mass 8kg is attached to massless string of length 2m and swum with a tangential velocity of 3 what is the tension on the string
Answers
Answer:
36 N
Explanation:
If the object of mass, m = 8 kg is swung in a horizontal circle of radius, r = 2m = length of string with tangential velocity v = 3 m/s, the tension in the string is the centripetal force which is T = mv²/r
= 8 kg × (3 m/s)²/2 m
= 4 kg × 9 m/s²
= 36 N
