K.C.S.E Physics Q & A - MODEL 1996PP2QN01

(a) A accelerates uniformly from it initial velocity, u, the final velocity, v in time t. The distance traveled during this time is S. If the acceleration is denoted by the letter, a show that;
(i) V = u + at
(ii) S = ut + at²
(iii) V² = u² + as
(b) A body moving initially at 50m/s decelerates uniformly at two 2ms^-2 until it comes to rest. What distance does it cover from the time it started to decelerate
