Text Solution

Verified by Experts
The correct answer is:
A

To determine the acceleration of the particle, we start by differentiating the displacement function with respect to time .

The displacement of the particle is given by:

First, compute the velocity by differentiating with respect to :

This gives:

Next, determine the acceleration by differentiating the velocity function with respect to time :

Calculating this gives:

Hence, the acceleration of the particle is
