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
B
It decreases with time
C
It remains constant
D
It 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.

Two satellites are launched at a distance $R$ from a planet of negligible radius. Both satellites are launched in the tangential direction. The first satellite launches correctly at a speed $v_0$ and enters a circular orbit. The second satellite, however, is launched at a speed $\frac {1}{2}v_0$ . What is the minimum distance between the second satellite and the planet over the course of its orbit?
