The answer is 8 meters per second 8m/s because 200 divided by 25 is 8
Answer: 5 m, 2 s
Explanation:
gravity is roughly 10 m/s²downward
That means in one second, the velocity will have been reduced to zero
The average speed is (10 + 0) / 2 = 5 m/s
h = vt = 5(1) = 5 m
It will take as long to fall back to the thrower from rest so total flight is 1 + 1 = 2 s

Explanation:
Answer:
The acceleration towards the center will be
Explanation:
Given the running track is an oval shape, and the diameter of each half-circle is 74 meters.
Also, the runner took 1 minute and 40 seconds to complete 400 m one round of the track.
We need to find the acceleration towards the center.
First, we will find the speed.
Where is the speed.
is the distance covered by the rider that is 400 meters.
is the time taken by the rider to complete the lap which is 1 minute and 40 seconds. seconds.
So,
And
Where is the acceleration towards the center.
is the radius which will be the half of the diameter 74 meters.
Hence, the radius will be 37 meters.
So, the centripetal acceleration of the rider will be
