**A golf ball of mass 46 g is struck a blow by a club....**

Hi,

I've been going through some past exam papers for the physics paper I'm doing (I got my exam tomorrow), and I came across this question:

A golf ball of mass 46 g is struck a blow by a club such that the impulse imparted to the ball makes an angle of 25˚ with the horizontal. The ball lands 200 m away on a level fairway, bouncing inelastically off the fair way at an angle of 20˚ for a second 10 m hop and successively moving on until it comes to rest. Assume air resistance is negligible and ignore any effects due to spin in what follows below.

(a) If the golf club and ball are in contact for 7.0 ms, determine the average force of impact

I can't seem to work out how to get the answer, I'm thinking it's got to do with impulse and projectile motion... yet... I am totally lost. Any guidance would be greatly appreciated.

Cheers
