Question

The velocity of a certain body is V=at^2 + b . Then the unit of 'a' is a) ms^-2 b) ms^-1 c) ms d) ms^-3​

Answer 1

Answer:

v = at² + b

To FinD :

Unit of a

SolutioN :

We're given equation, v = at² + b

Where,

v is velocity

t is Time interval

a and b are constants

⇒v = at²

As we know that unit of velocity is m/s. So,

⇒m/s = a * s²

⇒a = m/s(s²)

⇒a = m/s³

d) Unit of a is m/s³

Some Additional Information :

Velocity is defined as rate of change of displacement.

SI unit of velocity is m/s.

Velocity is a vector Quantity.

Answer 2

Answer:

unit of a ms^-3

Step-by-step explanation:

listen at ^2 will have same unit as velocity compare both v m s inverse is at ^2

ms^-1/s^2 or ms^-3
