Homework Statement

A 10.0kg box is accelerated from rest to 4.00 m/s in 1.00s. The force of kinetic friction on the box is 5.00N.
A) What is the size of the applied force?

B)What is the coefficient of sliding friction?

Homework Equations

The five kinematic equations?
μ = Ff/Fn
Fn= mg

The Attempt at a Solution

No idea.

You start by drawing a diagram of the forces acting on the box, and then use Newton's second law.
