Answer 2

Answer:

Hence, now the total momentum = m1v1+m2v2

Acceleration of car (a) = (v2–u2)/t

Also, f = ma

F1 = force exerted on the car by the truck.

F1 = m2(v2−u2)/t

Acceleration of the truck = (v1−u1)/t

F2 = m1(v1−u1)/t and F1 = −F2

M2(v2−u2)/t = −m1(v1−u1)/t

m2v2−m2u2 = −m1v1+m1u1

Or m1u1+m2u2 = m2v2+m1v1
