11PRACTICE PROBLEM
One end of a frictionless board of length L is raised to an elevation of E above the ground. The other end is in contact with the ground. The setup forms a ramp. The ramp makes an angle of α with the horizontal. An object at the top of the ramp is released from rest. Write the formula that describes the speed of the object when it touches the ground.
