Question

The relation between the partical's distance (S) and time (t) is S = a + b + ct² + dt³ ;
a, b, c & d ------ Which represents the dimension of acceleration?

Answer 1

The dimensions of all the terms between + is the dimension of distance [L]
so [a]=[L]
[B]=[L]
[Ct^2]=[L]
[C]=[L/S^2]
that is same as dimension of acceleration
