Answer:
Average force will be equal to 2908.57 N
Explanation:
We have given mass of the ball m = 46 gram = 0.046 kg
Let velocity at which ball is projected is u m/sec
Angle at which ball is projected
Range of the ball is given R = 200 m
Range is equal to
u = 44.27 m/sec
Change in momentum of the ball is equal to
Time of impact is given
Force is equal to rate of change of momentum
So force
Force will be equal to 2908.57 N
