A 1000. kg remote-controlled stunt car traveling at 17.0 m/s north collides with a 900. kg remote-controlled stunt car traveling at 18.0 m/s east. What is the speed of the entangled cars immediately after the collision? 7.2 m/s 7.7 m/s 10.2 m/s 12.4 m/s

Solutions

Expert Solution

Given:

Mass of car 1,

The first car is travelling at 17m/s north (+ve y-direction)

So the initial velocity of car 1,

Mass of car 2,

The second car is travelling at 18m/s east(+ve x-direction)

So the initial velocity of car 2,

After the collision, the cars get entangled

Find the final velocity of the cars

-------------

Consider the collision

During collision momentum is conserved

Initial momentum = Final momentum

--------

Magnitude

ANSWER: 12.4m/s
