Railroad Boxcar

A 6.1-kg object hangs at one end of a rope that is attached to a support in a railway carriage. ?

when the car accelerates to the right, the string makes an angle of 20 degrees to the vertical. Find the car accerlation. I noticed that the acceleration of the vehicle and the objects must be identical. How can I determine what is Thomas?

Thinking in terms of "g" forces and balance! OK!
