I'm having trouble with 2 problems here, I will give all the info that I am given but I still can't seem to solve the problems.

1.) A block(m1) is released from the top a curved sloped plane and elastically collides with another block(m2).

a.)How high does m1 go up the sloped plane after the collision?

b.)What is the velocity of m2 after the collision?

*Keep in mind that the system is frictionless

2.)Two blocks(M and 3M) are compressing a massless spring and are connected by a rope. The rope is then burned and the blocks release in opposite directions, block 3M goes at a velocity of 2m/s

a.) What is the velocity of block M?

*this system is frictionless as well.
