Question

A car accelerates at a rate 5 m/s2 . find the increase in momentum of the car of mass 100 kg in 2s.​

Answer 1

Answer:

1000 kg m/s

Step-by-step explanation:

m = 100 kg

u=0

t=2s

acc = 5 m/s^2

then v= t*acc

          =2 * 5

         = 10 m/s

momentum ( 1 ) = m * u

                   =100 * 0

                    = 0

 momentum ( 2 ) = m * v

                   =100 * 10

                    = 1000 kg m/s  

difference = 1000 kg m/s
