Question

A body moved on x-axis at time t secs, the displacement of the particle from the origin is x-metre and the velocity of the particle is vm/s when t=0, s=0 and v=0. 1) given that the particle moves at a constant acceleration and that v=1 when t=4, find a)the value of acceleration b) the value of x when t=4 2) given instead that the acceleration of the particle at time t secs is -3/8(t-2) squared m/s squared. A) show that v=1 when t=4 b) find x when t=4
