Question

The displacement (x) of a particle is given by, x = 2t. Find the acceleration of the particle. (t is time in second)

Answer 1

Correct Answer - Option 1 : 0

CONCEPT:

• Velocity (v): The rate of change of displacement is called velocity.

\(\vec v = \frac{{\overrightarrow {dx} }}{{dt}}\)

• Acceleration (a): The rate of change of velocity is called acceleration.

a = dv/dt

CALCULATION:

Given that:

x = 2t

velcoity, v = dx/dt = 2 m/s

acceleration, a = dv/dt = 0 

Hence option 1 is correct.
