Question

What is the magnitude (size) and direction of the cumulative force acting on the car shown in the picture above?
A.
2500 N up
B.
30 N to the right
C.
30 N to the left
D.
2500 N down

Answer 1

The vertical forces cancel, so only the horizontal forces are included in the net force. If the right is positive and the left is negative, then

50 N + (-20 N) = 30 N

so the net force is (B) 30 N to the right.

Answer 2

Answer:

(B) 30 N to the right.
