Explanation / Answer

after force is removed accceleration will be

a = - f / m = - uk m g / m = - uk g

a is independent of mass.

(a) initial velocity is same and acc will be same.

so distance will also be same.

distance = d

(b) now u = 2 v

then vf^2 - vi^2 = 2 a d

0 - 4 v^2 = - 2 a d'

d'= 2 v^2 / a

initially, d = v^2 / 2 a

d' = 4 d

Ans" 4d
