weight of the car is 1500kg
velocity of car is at first moment is 36km/h = 36* 5/18
= 10m/s
then,
velocity of the car at second moment is 72km/h=72* 5/18= 20m/s
Now,
change in momentum,
= momentum during 2nd moment - momentum during 1st moment
m2v2- m1v1
1500kg*20m/s - 1500kg * 10m/s
30000-15000
15000kgm/s. ans...
