please help me.A 5.00 g object moving to the right at +20.0 cm/s makes an elastic headon collision with a 10.0 g object that is initially at rest.
(a) Find the velocity of each object after the collision.
5.00 g object
10.0 g objectt
(b) Find the percentage of the initial kinetic energy transferred to the 10.0 g object.

I will help you by checking your work. This is an algebra intensive problem. Start with the conservation of momentum, solve one velocity in terms of the other, then substitute that into the conservation of energy. Finally, after manipulation, use the quadratic formula.
