The function s(t)=212+7t+3 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=4, 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). v(t)= (Do not factor.)
