Mikel runs with a speed of 3 m/s for 45 seconds. How far does mikel run?
Answers
Answer:
d = s • t
3m/s • 45s and and the seconds will cancel out.
135 meters
Answer:
velocity=3m/s
time=45sec
displacement=?
Explanation:
we have
velocity=displacement/time
3m/s=displacement/45
displacement=3×45=135m
Mikel runs 135m far.

Explain What the core muscles do and why it's important to have a strong set of core muscles.
Answers
Answer: Core muscles protect the spine and keeps it stabilized. Also they can help control movements such as walking and standing. The core helps transfer energy and help us move in different directions. It's important to have a strong set of core muscles.
Explanation:
Answer:
The core muscles stabilize and protect the spine. They help control all movements and make it possible for us humans to walk and stand up right. The core helps us transfer energy, shift our body weight and reach/move in different directions. It is important to have a strong set of core muscles because it makes everyday activities easier.
Explanation:
A 136 kg defensive lineman is about to tackle a 100 kg quarterback. Right before
impact, the lineman is moving north at 6.0 m/s and the quarterback is moving
north at 1.0 m/s. Determine the speed and direction of the two players
immediately after the tackle.
Answers
Answer:
3.88 m/s North
Explanation:
We are given that
[tex]m_1=136kg[/tex]
[tex]m_2=100 kg[/tex]
[tex]v_1=6 m/s[/tex]
[tex]v_2=1m/s[/tex]
We have to find the speed and direction of the two players
immediately after the tackle.
Using linear conservation of momentum
[tex]m_1v_1+m_2v_2=(m_1+m_2)v[/tex]
Substitute the values
[tex]136\times 6+100\times 1=(136+100)v[/tex]
[tex]916=236v[/tex]
[tex]v=\frac{916}{236}[/tex]
[tex]v=3.88m/s[/tex]
Direction of the two players immediately after the tackle is North.

Why do you think that if you drop two balls, exactly two balls rise on the other side at a

Answers
Answer:
It conserves both energy and momentum in the collision at the same time. By design, when the balls collide the strings that hold them up are vertical (assuming balls are only swung from one side).
