##### Reference no: EM13544447

A 5.0-kg object is pulled along a horizontal surface at by a 15 N force acting 20? above the horizontal.

(a) How much work is done by this force as the object moves 6.0 m?

(b) If the frictional coefficient between the object and the surface is 0.2 how much of the work is "lost" to friction during these 6.0 m.

(c) What is the velocity of the object after 6.0 m if the object starts at rest?

(d) How much work is done by the gravitational force?

(e) How much work is done by the normal force?
