Answer:
116 N.
Explanation:
Given,
mass of the ball, m = 0.145 Kg
initial speed = 0 m/s
Final speed = 40 m/s
time = 50 ms = 0.05 s
Force is equal to change in momentum per unit time
F = 116 N
Force of the pitcher hand on the ball is equal to 116 N.

Answer:
Explanation:
<u>Given the following data;</u>
Initial velocity = 0 (since the stone is starting from rest).
Final velocity = 32 m/s
Acceleration = g = 10 m/s²
Time = 3.2 seconds
To show that the speed of the stone when it hits the ground is 32 m/s, we would use the first equation of motion;
Where;
- V is the final velocity.
- U is the initial velocity.
- a is the acceleration.
- t is the time measured in seconds.
Substituting into the formula, we have;
<em>Proven: 32 m/s = 32 m/s</em>
