Homework Statement



The diagram provided shows a man pulling a box across the floor. Assume that the force of the friction can be ignored and that the acceleration of the box is 1.27 m/s. Find the angle to the horizontal that the man must pull.

65N figure located on the rope the person is pulling
15 kg is the mass of the box
Angle is theta so basically the variable that needs to be found


Homework Equations


Fnet=ma
Fnet=Fcos[theta]
I believe these equations are involved


The Attempt at a Solution


Not sure how to put this altogether and solve. Dont have an answer sheet so i can't check the answer. :(

Hi Dcpc10! Welcome to PF! :wink:

Use components of force and acceleration in the horizontal direction …

what do you get? :smile:
