Question

The following forces act on an object: 13.5 N towards West, 21.2 N towards East, 33.0 N towardsEast, and 25.3 N towards West. Calculate the net force acting on the object.

Answer 1

Answer:

Assign positive direction to the West directed forces then that also means negative direction has automatically been assigned to East directed forces . Now their sum with sign convention :-

F = +13.5N -21.2N -33N +25.3N

F = +38.8N -54.2N

F = -15.4N

Which means 15.4N towards East .
