Answer 1

Answer:

(a)

Given

   v = a √x

   x = 0 when t = 0

v = dx / dt =  a √x

=>  dx/√x = a dt 

integrate on both sides

=>  2 √x = a t +  c

   x = 0 at t = 0  => c = 0

=>  x = a²t²/4          differentiate now: wrt t

=>  v = a² t /2            differentiate now wrt t

=>  acceleration = a² / 2
