A 100 gram bullet travelling at 350 m/s strikes and sticks into a stationary 5.00 kg block of wood. The combined bullet+ block initially slides on a horizontal frictionless surface until they encounter a 30.0 degree inclined plane with a coefficient of kinetic friction between the bottom and the plane of the block of 0.350. To what maximum height will the center of mass of combined block and bullet rise above its original vertical situation?
