$) A 3.00 kg crate is at rest in front ofa compressed spring loaded with 40.0 J of elastic
potential energy at point A. The spring is released and the crate is propelled uphill. The crate
passes point B, which is 0.20m above point A at a constant speed. Assume that the surface
between point A and B is extremely slippery.
