A worker pushes horizontally on a 38 kg crate with a force of magnitude 114 N. The coefficient of static friction:

A. Determines the kinetic friction between the worker and the crate.

B. Is irrelevant to the motion of the crate.

C. Affects the normal force acting on the crate.

D. Will cause the crate to move if it exceeds a certain value.

The coefficient of static friction determines whether the crate will move or not, while the coefficient of kinetic friction affects the magnitude of friction in motion. The coefficient of static friction also affects the normal force acting on the crate.a) Determines the kinetic friction between the worker and the crate.

Explanation:

The coefficient of static friction determines whether the crate will move or not. If the applied force exceeds the maximum force of static friction, the crate will start to move. On the other hand, the coefficient of static friction is irrelevant to the motion of the crate once it is already in motion. In this case, the coefficient of kinetic friction determines the magnitude of friction between the worker and the crate.

The coefficient of static friction affects the normal force acting on the crate. The normal force is the force exerted by a surface to support the weight of an object resting on it. If the coefficient of static friction becomes larger, the normal force acting on the crate will also increase.
