How to solve MomentumProblems

1) Momentum is defined as p=mv it is a vector quantity2) So if we know the mass and velocity , we

can momentum easily. 3) The momentum of system is equal to

vector sum of momentum of the object with in it

4) The change in momentum of body is equal Force applied X time taken

p2-p1=Ft

What is Momentum

A golfer hits a golf ball of mass .2 kg and the ball leaves the club with the velocity 10 m/s. The ball and club remain in contact for .006s1) Find the average force exerted by the club on the ball2) Find the ball’s final momentum

Question

1)First get a clear picture of the problem2)Here the momentum change is due to force exerted by club on the ballSo Ft=p2-p1

Fx.006=.2X10 -0F=666 N3) Final momentum is given by momentum formula p2=mv=2 kgm/s
