The 88-lb force P is applied to the 210-lb crate, which is stationary before the force is applied. Determine the magnitude and direction of the friction force F exerted by the horizontal surface on the crate. The friction force is positive if to the right, negative if to the left. Assume 0.47, 0.35.

Explanation:

From the question we are told that:

Force P=88Ib

Mass of crate M_c=210Ib

Generally the equation for Frictional force F is mathematically given by

with

Therefore since Static Friction supersedes applied force body remains at rest.

Frictional force =88Ib (negative)

the answer is c.)

explanation:

the force required to move the cart is divided by three or 33.33 n.
