Question

A 1650 kg car accelerates at a rate of 4.0 m/s^2. How much force is the car's engine producing?

Answer 1

F = M A

Force = (mass) x (acceleration) 

                   = (1,650 kg) (4 m/s²) = 6,600 kg-m/s² = 6,600 Newtons

Answer 2

According to Newtons laws of motion F = MA. This means Force = Mass x Acceleration.

So...

4 x 1650 = 66,000
The units for Force is Newtons

So the answer is 66,000 Newtons
