Solution

$D e a r S t u d e n t, H e r e, u = 55 k m / h o u r = 15.28 m / s e c v = 90 k m / h o u r = 25 m / s e c t = 30 s e c a c c e l e r a t i o n, a = \frac{v - u}{t} \Rightarrow a = \frac{25 - 15.28}{30} \Rightarrow a = 0.324 m / s e c^{2} T h e r e f o r e, a c c e l e r a t i o n o f t h e c a r i s 0.324 m / s e c^{2} R e g a r d s$
