Question

Acceleration is defined as the rate of change of velocity. Unit of rate of change of acceleration is:

• A. $m/s^2$
• B. $m/s^3$
• C. $m/s$
• D. $m^2/s^3$

Answer 1

The correct option is B $m/s^3$

Acceleration has unit $m/s^2$.

The rate of change of acceleration $\frac{d\overrightarrow{a}}{dt}=\frac{d^{3}y}{d{t}^3}=\frac{m}{s^3}$

Hence, option B is correct.
