Here in all such collision type question we can use momentum conservation as we can see that there is no external force on this system
as we know that
now from above equation we have
so the speed of combined system is 2 m/s
Answer:
The car's angular speed is .
Explanation:
Angular velocity is usually measured with , so I'm going to use that to answer your question.
The relationship between tangential velocity and angular velocity (ω) is given by:
Using the values from the question, we get:
Therefore, the car's angular speed is .
Hope this helped!
