MCQ
A car is moving in a spiral starting from the origin with uniform angular velocity. What can be said about the instantaneous velocity?
- ✓It increases with time
- BIt decreases with time
- CIt remains constant
- DIt does not depend on time
✓
Answer
Correct option: A.
It increases with time
$a.$ It increases with time
Explanation:
This type of motion can be called circular motion with increasing radius. As the radius increases, the tangential velocity increases $(v = rw).$ Now, as there is only one velocity present, the speed will be equal to the magnitude of the tangential velocity.
