Camping equipment weighing 6000 N is pulled across a frozen lake by means of a horizontal rope.The coefficient of kinetic friction is 0.05.The work done by the campers in pulling the equipment 1000 m at constant velocity is:

Question

Quizplus · Accepted Answer

The work done is calculated using the formula: Work = Force x Distance. The force of friction is the product of the coefficient of kinetic friction and the normal force (which is equal to the weight of the equipment, 6000 N). Thus, the force of friction is 0.05 x 6000 N = 300 N. The work done over 1000 m is 300 N x 1000 m = 3.0 x 10^5 J.
