This is a short answer type question as classified in NCERT Exemplar
(a) x (t)=x0 (1- )
V (t)=dx/dt= x (t)=x0 ( )
A (t)= x ( t)=x0 ( )
(b) when t=o x (t)= x (t)=x0 (1- )= x (t)=x0 (1-1)=0
x (t) is maximum when t=
x (t) is maximum when t=
v (t) is maximum when t= , v (0)=x0
v (t) is maximum when t= v ( )=0
a (t) is maximum when t= , a ( )=0
a (t) is maximum when t= , a ( )=-x0 2
