Two forces are applied to a car in an effort to move it, as shown in the figure below. (Let F 43S N and 2 373 N. Assume up and to the right are in the positive directions.) l0*Explanation / Answer
4] The net force on the person in the elevator is:
R - mg = ma

=> 67[9.8 + a] = 828
=> a = 2.5582 m/s2.
