A particle is travelling with velocity v(t) = (+ + t)i + 2tj - sin(t)k The acceleration of the particle at t - 0 is a(0) = it K A particle is travelling with velocity v(t) = (t2 + t)i + 2tj - sin(t)k. Suppose the initial position of the particle is zi + j + (1 - cos(1) )k. The position of the particle at t = 1 is I(1) = K
