A Bus of mass 500 kg is moving with a velocity of 5 metre per second and is acted upon by a forward force of 500 Newton due to engine and retarding force of 200 Newton due to friction. Velocity of bus after 20 seconds will be:

Given, m = 500 kg, u = 5 m/s and t = 20 s. Resultant force, F = 500 – 200 = 300 N Acceleration, a = F/m = 300/500 = 0.6 m/s² by question of motion: v = u ...
