Hey, I'm stuck on this problem. If someone could point me in the right direction, it'd be greatly appreciated.

: Two objects of the same mass, m = 1.00 kg, are projected towards each other. The first object initially has velocity (20.0m/s)i^. The second object has initial velocity (-10.0m/s)i^ .After the glancing collision, the first object goes off with angle 2.00˚ above the positive x-direction and the second object goes off with angle 5.00˚ below the negative x-direction.

a. What is the speed of object 1 after the collision?
b. What is the speed of object 2 after the collision?
c. What is the change in kinetic energy in the collision?
d. Is this collision elastic or inelastic? Explain.
