Question

a car of mass 6 quintal is moving with a speed of 60 kmph hit an another car which is coming with 50 kmph in the opposite direction and stops exactly at that .calculate the weight of another car

Answer 1

Explanation:

from conservation of linear momentum

we get that

(note-we have to use the vector also)

m1v1=m2v2

6*60=50*m2

m2=7.2quintal

1quintal =1000kg
