Average force acting on 900 kg car if it's velocity ranges from 5 m s^-1 to 30 m s^-1 in 12 s is {{}} A)1875 N B)2000 N C)3000 N D)1560 N

Question

Quizplus · Accepted Answer

The average force can be calculated using the formula F = m * Δv / Δt, where m is the mass, Δv is the change in velocity, and Δt is the change in time. Here, Δv = 30 - 5 = 25 m/s, m = 900 kg, and Δt = 12 s. So, F = 900 * 25 / 12 = 1875 N.
