Question

a bike of mass 100 kg is moving with velocity 10 metre per second after applying the break the body comes to rest in 5 seconds what is its work done

Answer 1

m = 100 kg

u = 10 m/s

t = 5s

v = 0 m/s

Work done = Force × distance

Force, F = 100 × 2 = 200 N

distance, s = 50m

Work done = 200 × 50 = 1000 J

Hope this answer helps you ^_^ !
