Physics

Q. A block of mass 4kg is at rest on a level frictionless surface. A second block, of mass 9kg slides in to it with a speed of 15m/s and the two stick together. They slide up a slope until they come to rest. How high (in meters) off the level surface do the two reach before sliding back?

please explain how you solved for this so that I could learn.
