I am really stuck on this question, please help! THANK YOU!!
A golf club collides elastically with a golf ball and gives it an initial velocity of 60ms^-1. If the ball is in contact with the club for 15ms, and the mass of the ball is 2.0x10^-2 kg, calculate the size of:
a) the impulse given to the ball
b) the impulse given to the club
c) the initial kinetic energy to the ball
d) the average force exerted on the ball by the club
e) the work done on the ball and note the relationship between the work done on the ball and the initial kinetic energy to the ball
