The equation of motion of a particle $\"\"$ .

(a)

The velocity of a particle is differentiation of the equation of motion.

$\"\"$

Velocity of the particle as a function of $\"\"$ is $\"\"$ .

The acceleration of a particle is differentiation of velocity.

$\"\"$

Acceleration as a function of $\"\"$ is $\"\"$ .

(b)

The acceleration after 2 seconds:

Find the acceleration at $\"\"$ sec.

$\"\"$

(c)

The acceleration of a particle when velocity is zero.

$\"\"$

At time $\"\"$ sec, the velocity is zero.

The acceleration is

$\"\"$

When velocity is zero, the acceleration is $\"\"$ .

(a) $\"\"$ .

(b) The acceleration after 2 seconds $\"\"$ .
