<u>Answer:</u>
The ball fall vertically 2.69 ft by the time it reached home plate 60.0 ft away.
<u>Explanation:</u>
Fastest recorded pitches major-league baseball, thrown by nolan ryan in 1974 = 100.8 mi/hr = 44.8 m/s
The horizontal distance to home plate = 60.0 ft = 18.288 m
We have the horizontal velocity = 44.8 m/s
So time taken = 18.288/44.8 = 0.408 seconds.
The distance traveled by baseball vertically is found out by equation 
Here u =0m/s, a = 9.81 
and t = 0.408 s
Substituting
So vertical distance traveled = 0.82 m = 2.69 ft

Answer:
4.465 m
Explanation:
Taken the beam to be uniform, then the center of gravity will act at the mid-point of the beam. The mid point = 11 / 2 = 5.5 m
since the boy can walk to the end of the beam without falling,
then the torque ( moment of the force) by beam = torque by students at the end of the beam
let the distance of the boy = x
220 ( 5.5 - x ) = 51 × x
1210 - 220 x = 51 x
1210 = 51 x + 220 x
1210 = 271 x
x = 1210 / 271 = 4.465 m
Answer:
Explanation:
When an object strikes the ground, the potential energy of the rock gets converted to the kinetic energy.
A rock is dropped from a distance 
above the surface of the earth and is observed to have kinetic energy 
when it hits the ground.
For another rock, It is dropped from twice the height 
above the earth’s surface and has kinetic energy 
when it hits.
For the first rock, 
..............(1)
For the second rock, 
..............(2)
Dividing equation (2) by (1) we get :
Hence, this is the required solution.
