Question

a 1200 kg car goes from 0 m/s to 26.8 m/s in 4s. what is the average force acting upon it?

Answer 1

Answer #1

Ans: mass= 1200 kg.

Initial velocity is 0 m/s at time 0 second.

Final velocity is 26.8 m/s at time 4 second.

Acceleration= (final velocity - initial velocity)/( final time - initial time).

Acceleration= (26.8m/s)/4 second

= 6.7 meter/ second square

Force= mass × acceleration

= 1200 × 6.7 Newton

= 8040 Newton
