## Homework Statement

A point moves rectilinearly with a deceleration whose modulus depends on the velocity v of the particle as

a=(alpha) X (square root of velocity v),

where alpha is a positive constant. At time t=0, the particle has initial velocity v1.

Then, what are the following:

i. Time taken by the particle to come to rest

ii. The distance traveled before it stops

iii. The time at which the instantaneous velocity is (v1)/4

iv. Distance traveled at the time the velocity becomes (v1)/4.

## The Attempt at a Solution

I tried to integrate the equation but ended up no where because of the v term in the given equation, which kept getting in my way...PLEASE HELP!

I want to learn how to solve such problems which involve such variables in their equations...
