Question

A golfer hits a ball at rest such that the contact between the ball and the golf stick is for 0.1s. If the golf ball covers a linear distance of 400m in 2s,calculate the magnitude of the force applied assuming that the mass of the ball is50g

Answer 1

velocity will be 400 / 2 is equal to 200 m per second. look for finding force we will find change in momentum and divide it by time..=50*0.001*2*200/0.1=200N... as initial and final Momentum will be in opposite direction
