The function sit) =t3 3t+ 2 gives the distance from a starting point at time t of a particle moving along a line. Find the velocityr and acceleration functions. Then nd the velocity and acceleration att= ID and t: 4. Assume that time is measured in seconds and distance is measured in centimeters. Velocity will he in centimeters per second (cmi'sec) and acceleration in centimeters per second per second {cmrsec2). The velocity function is vtt) = D. [Simplify your answer.) The acceleration function is a(t}= El. [Simplify your answer.) The velocity at t: 0 is v{U} = D cmlsec. [Simplify your answer.) The velocity at t: 4 is v{4} = D cmlsec. [Simplify your answer.) The acceleration at t: D is all?) = D cmi'sec2. [Simplify your answer.) The acceleration at t=4 is at4) = D cmi'sec2. [Simplify your answer.)
