Question

There are two forces acting on an object. One force has a magnitude of 39 N and is directed along the +x axis. The other force has a magnitude of 25 N and is directed along the +y axis. What is the direction of the acceleration of the object? Express your answer by giving the angle between a and the x axis.

Answer 1

The direction of the acceleration is the direction of the resultant force. That direction makes an angle of
arctan(25/39) = 32.7 degrees with the +x axis, measured counterclockwise from the +x axis.

Answer 2

Thank you!
