Alex and John are loading identical cabinets onto a truck. Alex lifts his cabinet straight up from the ground to the bed of the truck, whereas John slides his cabinet up a rough ramp to the truck. Which statement is correct about the work done on the cabinet–Earth system? (a) Alex and John do the same amount of work. (b) Alex does more work than John. (c) John does more work than Alex. (d) None of those statements is necessarily true because the force of friction is unknown. (e) None of those statements is necessarily true because the angle of the incline is unknown.

Expert Solution & Answer

To determine

The correct statement about work done on the cabinet earth system.

Answer to Problem 1OQ

Option (c).

Explanation of Solution

Considering the cabinet has negligible speed during the operation. Of all the work A does increases the gravitational potential energy of the cabinet earth system.

In additional to increasing the gravitational potential energy of the cabinet earth system by the same amount as A did, john does an extra work in overcoming the friction between the cabinet and the ramp.

Therefore, total work done by the john is more than A.

Conclusion:

Since the total work done by the john is greater than that of A, option (c) is correct.

The total work done by the john is greater than that of A. Thus, option (a) is incorrect.

The total work done by the john is greater than that of A. Thus, option (b) is incorrect.

The total work done by the john is greater than that of A. Thus, option (d) is incorrect.

The total work done by the john is greater than that of A. Thus, option (e) is incorrect.

The total work done by the john is greater than that of alex. Thus, option (E) is incorrect.
