7. A 3.0-kg mass is sliding on a horizontal frictionless surface with a speed of V=3.0 m/s when it collides with a 1.0-kg mass initially at rest as shown in the figure. The masses stick together and slide up a frictionless circular track of radius 0.40 m, as the drawing below shows. To what maximum height, h, above the horizontal surface will the masses slide. 0,40 m
