Question

A different car accelerated from 0.12 m/s to 0.52 m/s.

The acceleration of the car was 0.040 m/s².
The work done to accelerate the car was 0.48 J.
Calculate the resultant force needed to accelerate the car.

Answer 1

Initial velocity, v₀ = 0.12 m/s

Final velocity, v = 0.52 m/s

Acceleration, a = 0.040 m/s²

Work done, W = 0.48 J

F = 0.48 J / 0.4 m/s = 1.2 N ( Final Answer )
