Buster wants to demonstrate constantly-accelerated motion by letting a frictionless ice cube slide down an inclined plane. The ramp is L= 1.5 meters long. Buster can control the angle θ that the plane makes with the floor. He plans to release the ice cube from rest at the top of the ramp. If Buster wants the time the ice cube takes to completely slide down the ramp to bet= 2.0 s, what angle θ should the ramp make with the floor?
