In this problem, we have been given that there are two cars.
00:05
One of the car is having a mass of 1 ,674 kilograms, and the other car is having mass of 1 ,025 kilograms.
00:17
The first car is moving at a speed of 24 meter per second, so it collides with another car which is moving at a speed of 18 meter per second in the same direction.
00:28
And it's observed that after collision, both these cars, they stick together and they move as a single object.
00:37
So of course their velocity will be same.
00:39
So we need to determine their common velocity after collision.
00:43
So here as there is no external force acting onto the system of two cars, so the total momentum before collision will be equal to the total momentum after collision.
00:54
So here we just multiply their respective masses and the velocities...
