((60m/s+80m/s)/2)x12s=840m

When a golf club strikes a golf ball the force exerted by the ball on the club depends on

the mass of the ball and club and the velocity of the club

A force of 20 N gives a ball an acceleration of 4.0 ms on a level frictionless surface what is the mass of the ball

F=ma

m=F/a

m=20/4.0

m=5Kg
