Question

who is the champion in rotational machenics if you are then give me the answer of the question given

Answer 1

The velocity of the ball= 20m/s  Mass of the ball=150g=0.15kg Time taken by the ball to reach in hand of person = 0.1sec Acceleration=v/t                      = 20/0.1                      = 200m/s^2 Force           = mass                        ×acceleration                      = 0.15×200                      = 30 Newton
