Physics - Circular Motion Question with Solution | TestHub

PhysicsMediumassertion reason

Assertion: Speed of a particle moving in a circle varies with time as $v = (2 t + 1) m / s$ . Such a circular motion is possible.

Reason: Speed can change linearly with time when the tangential acceleration is constant.

Options:

Answer:

Solution:

Both are true: $v = 2 t + 1$ stays positive for all $t \geq 0$ , so the motion is possible; a constant tangential acceleration ( $2 m / s^{2}$ here) makes the speed change linearly, which is exactly why such motion is possible.
