the formula of change in momentum= mv - mu, where m=mass i.e 1500kg, v=final velocity i.e 72 km/hr, u=initial velocity i.e 36 km/hr. we will change the v and u to m/s i.e 72X5/18=20 m/s and 36X5/18=10 m/s.
= mv - mu
= 1500X20 - 1500X10
=1500[ 20 - 10 ]
= 1500 X 10
= 15000 kg m/s
= mv - mu
= 1500X20 - 1500X10
=1500[ 20 - 10 ]
= 1500 X 10
= 15000 kg m/s
