Non Uniform Circular Motion: Practice Problem & Solution

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Non Uniform Circular Motion. Understanding the underlying formula is key to arriving at the correct answer below:

As the speed of cyclist is increasing positive tangential acceleration is acting on the object. so net acceleration makes an acute angle with velocity.

As, net acceleration and net force will have same direction, angle between velocity and net force is acute. Work done will be positive.
