Question

Hi,

I believe the correct answer to this problem is B, since toaccelerate the magnitude of applied force must exceed the force offriction but I want to verify. Please let me know if you agree orif I'm wrong and why another answer is correct.

8. A manager of a restaurant pushes horizontally with a force ofmagnitude 150 N on a box of melons. The box moves across the floorwith a constant acceleration in the same direction as the appliedforce. Which statement is most accurate concerning the magnitude ofthe force of kinetic friction acting on the box?

A. It is greater than 150 N.

B. It is less than 150 N

C. It is equal to 150 N

D. The kinetic friction force if steadily decreasing.

E. The kinetic friction force must be zero.

Thanks,

Explanation / Answer

YOU ARE RIGHT .LET US ANALYZE ACANT BE TRUE. CIF MOVING WITHCONSTANT VELOCITY DIS WRONG.E CANT BE TRUE AS THE FLOOR IS NOT SMOOTH
