Find the velocity of the hockey puck at any time t. v(t) ===== b. Find the acceleration of the puck at any time t. -1 a (t) = (t) where s is in meters. c. Evaluate v(t) and a (t) for t = 1, 4, and 5 seconds. Round to 4 decimal places, if necessary. v (1) v (4) v (5) a (1) = = = = a (4) = a (5) = d. What conclusion can be drawn from the results in the previous part? ○ The hockey puck is decelerating/slowing down at 1, 4, and 5 seconds ○ The hockey puck has a constant velocity/speed at 1, 4, and 5 seconds ○ The hockey puck is accelerating/speeding up at 1, 4, and 5 secondsarrow_forwardquestion 8arrow_forward
