Question

The velocity of an object varies with time as

v = At2

+ Bt + C. Taking the unit of time as 1 sec

and velocity as m/ s, the units of A,B,C respectively

are

a) ms–3, ms–2, ms–1 b) ms–2, ms–1, ms–3

c) ms–1, ms–2, ms–3 d) ms–1, ms–1, ms–1​

Answer 1

Answer:

» v = At² + Bt + C

Therefore, A = m s^(-3)

» B = m s^(-2)

» C = m s^(-1)

Hence, option (a) is correct.
