Copy questions of motion in straight line for circular

Question

A particle is moving in a circular path of radius 1m with a uniform speed of 1m/s. What is its average acceleration during the journey from A to B?

Moderate

Solution

Time of journey $t = \frac{π \times 1}{1} S = πS$
Average acceleration $\frac{Δv}{t} = \frac{1 - (- 1)}{π} m / s^{2} = \frac{2}{π} m / s^{2}$
