A person pushes a stalled car with 400 N but the car does not move. The friction force on the car is
A.400 N opposite the push
B.zero
C.greater than 400 N
D.less than 400 N
Explanation
Core Concept
No motion means zero net force, so static friction matches the 400 N push.
Correct Answer
A400 N opposite the push
