1. A 1.5kg box starts from rest. There is a coefficient of friction of k = .3 between the box and the floor. How much work is done on the box as it moves from x=0 to x=2m by: a) F b) F2 c) Friction d) The normal force e) Gravity f) What is the net work done on the box? g) How fast is the block moving? You can use the Newtonian (F=ma) and kinematic approach or use the work and energy approach to get this answer. F = 5N 1.5kg 30 F = 20N
