Question

Two cars each of mass 1000 kg are moving in a straight line but in opposite directions. The velocity each car is 5m/s before the collision during which they stick together. What will be the velocity of the combined cars after collision?​

Answer 1

Answer:

$given... \\ \\ m1 = 1000kg \\ \\ m2 = 1000kg \\ \\ u1 = 5m {s}^{ - 1} \\ \\ u2 = 5m {s}^{ - 1} \\ \\ according \: to \: law \: of \: \\ conservation \: of \: mometum \\ m1u1 - m2u2 \\ = (m1 + m2)v \\ (1000 \times 5) - (1000 \times 5) \\ = (1000 + 1000)v \\ 5000 - 5000 = 2000v \\ 0 = 2000v \\ v = \frac{2000}{0} \\ \\ v = > 0 \\ \\ \\ \\ \\ \\ \\ \\ \\ hope \: it \: will \: help \: uh$
