3) A person pulls a box pictured below. The box slides up the ramp. F = 350 N, m = 50 kg, u = 0.15 and 0 = 30. a) Is the box moving a constant speed? Explain. m b) How much work is done by person (F) over a total distance of 10 m? c) How much work is done by friction over a total distance of 10 m? d) How much work is done by gravity over a total distance of 10 m? e) There seems to be an "unbalanced" amount of work done on the box. Where does that extra energy "go"? f) If the box started from rest, how fast would it be going after 10 m
