A 8.20-kg block of ice, released from rest at the top of a 1.56-m-long frictionless ramp, slides downhill, reaching a speed of 2.58m/s at the bottom.
1.) What is the angle between the ramp and the horizontal?
2.) What would be the speed of the ice at the bottom if the motion were opposed by a constant friction force of 10.9 Nparallel to the surface of the ramp?
