A car of mass 1000 kg increases its velocity from 10 m/s to 20 m/s in 5 seconds. What is the force exerted on the car?
2000 N
Acceleration, \(a = \dfrac{v-u}{t} = \dfrac{20-10}{5} = 2\ \text{m/s}^2\).
Force, \(F = ma = 1000 \times 2 = 2000\ \text{N}\).
Hence, this is the correct answer.(2000 N) is correct.
