Question

John pushes forward on a car with a force of 400 N while Bob pushes backward on the car with a force of 325 N. what is the net force on the car?
A. 75 n FORWARD
B. 725 N BACKWARD
C. 75 N BACKWARD
D. 725 N FORWARD

Answer 1

A) 75 N forward. You just subtract 325 N from 400 N

Answer 2

Answer: A. 75 N FORWARD

Explanation:

The net force is calculated by subtracting the force in one direction with the force in another direction.

Given : Forward force by John on a car = 400 N

Backward force by John on a car = 325 N

Thus net force is calculated by :

Net force = Forward force by John on a car - Backward force by John on a car

Net force = 400 N - 325 N = 75 N in forward direction.
