Homework Statement
A mass M = 74.0 kg is suspended by a massless string from the ceiling of a van which is moving with constant acceleration a, as shown in the figure.
If the string makes an angle theta = 22° with respect to the vertical, what is the acceleration a of the van?
Homework Equations
All I can think of is F=ma
The Attempt at a Solution
I found the force of the x component and the y component (-27.72N and 793.8N resp.) I tried 27.72=74.0a=.375m/s^2 and 793.8=74a=10.727m/s^2. I tried adding/substracting tthe answers. I don't know what to try anymore.
