A ball of mass 70gram is moving with a velocity of 0.5meter/second.A player stops the ball in 0.5second.?

Question

Calculate the force exerted by the player on the ball.

give answer in Newton and show full calculation.

Answer 1

According Newtons second law

Force = mass X Acceleration

         = Mass x (final velocity-initial velocity)/time

         = 70/1000 x (0-0.5)/0.5

         =0.07 N   ( - sign indicates here force is acting opposite to ball                                 direction)
