2 Dimensional Motion: Net force at an angle

[ayans2495]

Homework Statement

A mass of 40 kg, sitting on a smooth surface, is acted on by a force of 18 N eastward inclined upward at 30 degrees. Find the acceleration.

Relevant Equations

F=ma

 

[ayans2495]

My solution was to find the horizontal component of the net force and divide that by the mass. Am I right?

Your solution is correct.

 

[ayans2495]

Your solution is correct.

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

 

[Lnewqban]

Yes, it is.
