Question

a scooter moving at a speed of 10 metre per second is stopped by applying brakes which produce a uniform acceleration of -0.5 metre per second square how much distance will be covered by the scooter before it stop​

Answer 1

Answer:

Explanation:

u = 25m/s, v = 0, t = 5 s, m = 180 kg

pi = mu = 180 x 25

      4500 kg m / s

pf = my

   = 180 x 0

   = 0 kgm /s

pf - pi = 0 - 4500

         = -4500 kg m / s

Hence, the change in momentum is -4500 kg m/s.
