The function s(t)=-3+27t-8 gives the distance from a starting point at time t of a particle moving along a line. Find the velocity and acceleration functions. Then find the velocity and acceleration at t=0 and t=3. Assume that time is measured in seconds and distance is measured in centimeters. Velocity will be in centimeters per second (cm/sec) and acceleration in centimeters per second per second (cm/sec). The velocity function is v(t) = (Simplify your answer.) The acceleration function is a(t)= (Simplify your answer.) The velocity at t=0 is v(0) = cm/sec. (Simplify your answer.) The velocity at t=3 is v(3) = cm/sec. (Simplify your answer.) The acceleration at t=0 is a(0) = cm/sec. (Simplify your answer.) The acceleration at t=3 is a(3) = cm/sec.
