A 8.00-kg block of ice, released from rest at the top of a 1.32-m -long frictionless ramp, slides downhill, reaching a speed of 2.76m/s at the bottom. What is the angle between the ramp and the horizontal? What would be the speed of the ice at the bottom if the motion were opposed by a constant friction force of 10.5N parallel to the surface of the ramp?
