A force is applied to move a desk. If the desk has a mass of 10kg and accelerates at 2m/s^2 after a force of kinetic friction of 15 N is applied, with what force is the desk being pushed with



Answer :

MathPhys

Answer:

35 N

Explanation:

According to Newton's second law of motion, the net force on an object is equal to its mass times its acceleration. There are two forces on the desk in the horizontal direction: an applied force F pushing it forward, and a friction force of 15 N pushing backward.

∑F = ma

F − 15 N = (10 kg) (2 m/s²)

F = 35 N
