2 Dimensional Motion: Net force at an angle

Click For Summary
SUMMARY

The discussion centers on calculating the net force in two-dimensional motion, specifically focusing on finding the horizontal component of the net force and dividing it by mass to determine acceleration. Participants confirm the correctness of the method and the resulting acceleration value of 0.4 m s-2. This approach is validated by multiple contributors, establishing it as a reliable technique for solving similar physics problems.

Thank you for your reply. I also got a value of 0.4 m s^-2, is that also correct?
 
Yes, it is.
