Question

On his way off to college, Russell drags his suitcase 19 m from the door of his house to the car at a constant speed with a horizontal force of 89 N. How much work does Russell do to on the suitcase to overcome friction? Answer to the nearest Joule.

Answer 1

Answer:

The work done on the suitcase is, W = 1691 J

Explanation:

Given data,

The force on the suitcase is, F  = 89 N

The distance Russell dragged the suitcase, S = 19 m

The work done on the suitcase by Russell is equal to the work done on the suitcase to overcome the friction

The work done on the suitcase by Russell is given by the formula

                          W = F · S

Substituting the given values,

                           W = 89 N x 19 m

                           W = 1691 J

Hence, the work done on the suitcase is, W = 1691 J
