A car has a mass of 975 kg. by pushing on the car, evan increses its speed from 0.5 m/s to 3 m/s. what impulse did evan apply to the car?

A. 2925 kg m/s

B. 487.5 kg m/s

C. 2438 kg m/s

D. 1215 kg m/s

Impulse = change in momentum = F x dt

Where F is sufficiently large and dt is very small (tending to zero).

Therefore impulse = mass x final velocity - mass x initial velocity

= 975 x 3 - 975 x 0.5

= 2437.5 Kg-m/s.

Hence option C is correct.
