Question: An object moving along a horizontal surface approaches the bottom of a ramp. At the very bottom of the ramp, point A , its speed

An object moving along a horizontal surface approaches the bottom of a ramp. At the very bottom of the ramp, point A, its speed is 40 m/s. The object goes up the ramp and reverses direction at point B.
What is the height of point B above point A? The angle of inclination is 30. Neglect friction and use g =
10 m/s.
