What is the net force acting on a golf car travelling at constant speed of 5 mph

15 n

5 n

0 n

10 n

I think it is 5 newtons

The answer is 0 Newtons

This is because of a key word in the question: "constant"

When we say something has a constant speed, that means that its acceleration is 0.

Using the equation derived for Newton’s 2nd law, we see that F=ma

Force = mass x acceleration

If acceleration, a, equals 0, then when we multiply our mass times acceleration 0

F=m (0)

Anything times zero equals zero

So, F=0
