An 64000-kg car moving with velocity 30m/s strike another car 3200 kg moving in opposite with velocity 90 m/s. if the collision in perfectly inelastic collision. What is the velocity of the two cars?
Homework Answers
In this perfectly inelastic collision both cars will stick to each other after collision.
From momentum conservation..
m1v1 + m2v2 = Mtotal× Vfinal
So Vfinal =[64000×30 + 3200×(-90)] / (64000+3200)
Vfinal = 24.28 m/s
= 24.3 m/s
In the direction of massive car.
