if that is constant acceleration, a = (v-u)/t plug inthe numbers and you get the time elapsed.
*November 24, 2011*

**physics**

zero, by newton's 2nd law. having constant velocity, there is no change in its momentum over time. hence there is zero resultant force on it, and it has zero acceleration.

**physics**

it becomes slower as by newton's 2nd law, it undergoes a change in momentum, assuming its mass is kept constant. a resultant force acts in the opposite direction of its motion. hence it retards.
*November 24, 2011*

**physics**

acceleration = (final velocity minus initial velocity)/time taken. the formula is based on newton's 2nd law, which states that the rate of change of momentum of an object is directly proportional to the resultant force acting on it. F = m(v-u)/t ma = m(v-u)/t hence, a=(v-u)/t
