A 410-kg piano is being unloaded from a truck by rolling it down a ramp inclined at 25°. There is negligible friction and the ramp is 11.0 m long. Two workers slow the rate at which the piano moves by pushing with a combined force of 1300 N parallel to the ramp. If the piano starts from rest, how fast is it moving at the bottom?
