Question

Which of the following could not be a unit of acceleration?
(a) km/s2
(b) cm s−2
(c) km/s
(d) m/s2

Answer 1

Answer: The correct answer is km/s

Answer 2

Answer:

The correct answer is option (a) $km/s^{2}$.

Explanation:

Acceleration can be described as the rate of change of velocity with time. It can even be described as the growth in velocity per second.

Unit of acceleration exists the meter per second per second $(m/s^{2} )$. The newton exists that force that, when working on a mass of one kilogram, has an acceleration of one meter per second per second.

Therefore, the correct answer is (a) $km/s^{2}$.
