Ap physics F=ma

Question

Wat force is required to move a 2500 kg race car at 3 m/s²?

Answer 1

F = ma

where m = mass in kg and a = acceleration is m/s²

Both are given.

Force, then, = (2500kg)(3m/s²)

It is easier to work with smaller numbers, so let's call 2500 kg = 2.5 x 10³ kg

This leaves with you (2.5 x 10³)(3)

Your answer is 7.5 x 10³ or 7500.

The unit of force is Newtons, N = (kg)(m/s²)

7500 N
