4.)A 5kg object is sitting on a frictionless incline of 25 degrees, A) if the block moves down the incline 4m. Calculate the work done by gravity B) If we increase the mass, does the work done by gravity, increase, decrease or stay the same? C) Explain in sentences why the normal force does no work on the block as it moves down the ramp but the normal force would do work if the block was in an elevator moving up.
