## Homework Statement

A 4.62 kg block located on a horizontal floor is pulled by a cord that exerts a force F = 12.0 N at an angle θ = 33.0° above the horizontal.

The coefficient of kinetic friction between the block and the floor is 0.100. What is the speed of the block 3.10 s after it starts moving?

## Homework Equations

Fn = U

_{k}* (m*g - F*sin[tex]\theta[/tex])

F = ma

## The Attempt at a Solution

I solved for Fn and got Fn = 3.87. I assume I need to solve for acceleration and then get velocity but I am not sure.
