1. If a particle's velocity is given by v(t) : 2152 + 4 and its distance at t = 3 is d(3) = 5, then what is d(0)? 6. For an object Whose velocity is given by v(t) = cos(t), What is its displacement on the interval t = 0 to t = 2? 7. If the acceleration of a particle is given by the equation a(t) : 4t + 1, and the particle's velocity at time t : 1 is 21(1) : 2, what is the velocity of the particle at time t = 4? 8.
