Answer: Third option
F = 250w
Explanation:
The impulse can be written as the product of force for the time interval in which it is applied.
You can also write impulse I as the change of the linear momentum of the ball
So:
We want to find the force applied to the ball. We know that
milliseconds = 0.03 seconds
The initial velocity is zero.
The final speed
So
We must express the result of the force in terms of the weight of the ball.
We divide the expression between the acceleration of gravity
The answer is the third option
