A 0.200 kg bullet is fired horizontally at 5.5 x 10^2 ms^-1 at an armour plate. It strikes the metal surface at 45 degrees and is deflected off at the same angle with the same speed. Determine the:
a) change in momentum of the bullet
b) the force acting on the bullet if the collision with the plate takes 0.020 seconds
been having trouble trying to solve this, any help would be great
