The acceleration (a) and the velocity of...

The acceleration (a) and the velocity of a particle in rectilinear motion are related as a = `-sqrt(v)`. Then

A

if the particle comes to rest after 1 s its initial velocity = 0.25 m/s

B

if the initial velocityis `v_(0)` then after a time t velocity = `v_(0) - sqrt(v_(0))t+ (t^(2))/(4)`

C

if the initial velocity is `v_(0)` then after a fine t, velocity = `v_(0) `-at

D

if the initial velocity is 1 m/s the particle comes to rest after 2 s
