A 3KG SLUG BLOCK IS PUSHED UP AN INCLINED PLANE BY A HORIZONTAL FORCE OF 200LBS. THE ANGLEOF THE INCLINED PLANE IS 60 DEGREEABOVE THE HORIZONTAL. THE BLOCK STARTS FROM REST AND AFTER MOVING 10 FEET UP ALONG THE PLANE, IT IS MOVING UP AT 2FT/SEC. HOW MUCH WORK WAS DONE BY THE 200LBS FORCE? HOW MUCH MECHANICAL ENERGY WAS LOST ON THE CLIMB? WHAT IS THE NORMAL FORCE?
