Answer to Question #15706 in Mechanics | Relativity for nicole

Question

The force of friction acting on a sliding crate is 144N. How much force must be applied to maintain a constant velocity? (N)
What will be the nest force acting on the crate? (N)

Answer 1

According to first Newton’s law, if velocity is constant, the equally effective force is zero.
From this follows: applied force is 144N.
The nest force acting on the crate will be zero.
