## Homework Statement

A 5.86 kg block located on a horizontal frictionless floor is pulled by a cord that exerts a force F = 10.00 N at an angle = 35.0° above the horizontal (x-axis). What is the speed of the block 3.70 seconds after it starts moving?

## Homework Equations

Fcos() - ma = 0

Fsin() - mg = 0

V_f = V_0 + at (V_0 = 0)

## The Attempt at a Solution

Since the first two equations are equal to zero I set them equal to each other and then solved for acceleration. I then used this in the last equation to solve for V_f. Apparently I am doing something wrong because I am not getting the correct answer.
