A particle moves along a straight line with a retardations of av^(n+1) , where v is the velocity at time t and a is a positive constant. If at t = 0 the velocity of the particle is u, show that at = (1)/(n)((1)/(v^(n))-(1)/(u^(n))).

Velocity of a moving partical v decreases with its displacement. Given, v = v_(0) - alpha x where v_(0) = initial velocity ,x = displacement and alpha is a constant. How long will the partical take to reach a point B on the x- axis at a distance x_(m) from the origin?
