if position of a particle at instant t is given by x= t3.find the acceleration of the particle..

derieve the relation for uniformly accelerated motion along the straight line. s= ut + 1/2 at2where the symbols have their usual meaing....

Consider a body having initial velocity u,If it is subjected to an acceleration 'a' so that after time 't' its velocity becomes v.

acceleration=Change in velocity/time taken

a=(v-u)/t

v=u+at

Suppose the distance travelled by the above body in time t=s

we have average velocity=(Initial velocity+Final velocity)/2
