Question

The position of a particle at any time t is given by s(t) = (1-e«) where b > 0 and V, are constants. What
is the velocity of the particle at (A) t = 0; (B) t = 1/b and (C) to​

Answer 1

ANSWER

s(t)=aV0(1−eat)

⇒s(t) has the dimension of M0L1T0

aV0 should also have the dimension of  M0L1T0

⇒M0L1T0=aL1T−1

⇒a=T−1
