The velocity of a particle depends upon as v=a+bt+ct2v = a + bt + ct^{2}; if the velocity is in m/sec⁡m/\sec, the unit of aa will be

A

m/sec⁡m/\sec

B

m/sec⁡2m/\sec^{2}{}

C

m2/sec⁡m^{2}/\sec

D

m/sec⁡3m/\sec^{3}{}

Answer

m/sec⁡m/\sec

Explanation

Solution

Quantities of similar dimensions can be added or

subtracted so unit of a will be same as that of velocity.
