(a) A body accelerates uniformly from its initial velocity, u, to the final velocity, V, in time t. the distance travelled during this time is S. If the acceleration is
denoted by letter a, show that; (i) V = u + at (ii) #S = ut + 1/2 at^2# (iii)#V^2 = u^2 + 2as#(b) A body moving initially at 50m/s decelerates uniformly at #2 ms^-2# until it comes to rest. What distance does it cover from the time it started to decelerate?
