Block A with mass ma= 2kg is moving along x-axis. It collides with a block B with mass mB = 6kg that is moving in the positive direction of x-axis with speed VBO= 2m/s. After the collision block B is found to be moving in the positive direction of x-axis with speed vB= 0.5m/s and block A is found to be moving in the positive direction of x-axis with speed is vA= 2m/s. a) Find the velocity of block A before the collision (magnitude and direction). b) Was the collision elastic (needs proof)?

Block A with mass ma= 2kg is moving along x-axis. It collides with a block B with mass mB = 6kg that is moving
in the positive direction of x-axis with speed VB0= 2m/s. After the collision block B is found to be moving in the
positive direction of x-axis with speed vB= 0.5m/s and block A is found to be moving in the positive direction of x-axis
with speed is vA= 2m/s. a) Find the velocity of block A before the collision (magnitude and direction). b) Was the
collision elastic (needs proof)?
