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:

Unit of a is m/s³

Explaination:

Given

• v = at² + b

To Find:

• Unit of a

Solution :

Given equation - v = at² + b

Where,

• v is velocity
• t is Time interval
• a and b are constants

⇒v = at²

we know,

unit of velocity is m/s.

So,

=> m/s = a * s²

=> a = m/(s¹)×(s²)

=> a = m/s³

So, d) Unit of a is m/s³

hope it helps.
