Homework Statement

A block of mass 6.7 kg is pulled along a horizontal frictionless floor by a cord that exerts a force of 56.0 N at an angle 27.9o above the horizontal. What is the magnitude of the acceleration of the block?

Homework Equations

f=ma



The Attempt at a Solution

i split my x and y coordinates and got x and y accelerations then used c^2=a^2+b^2 to find the magnitude of the acceleration and got 8.63m/s^2 but iam getting it wrong, please help thanks

You only needed to find the x component of force and use F=ma to get the acceleration in the horizontal direction. The horizontal acceleration is the acceleration you're looking for.

Show how you wrote your net forces along x and y.
Is it possible to have acceleration along y?
