Given:
Particle Moves A to B as shown in figure.
To find:
Average acceleration ?
Calculation:
First of all, average acceleration is defined as the change in velocity divided by the time.
In uniform circular motion, change in velocity for a particular angular displacement is given as:
Let average acceleration be "a" :
Put = 90°
So, final answer is :
