Momemtum/Energy Problems?? 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.
