Please help me with the following questions.

1.

Part A A car is stopped at a traffic light. It then travels along a straight road so that its distance from the light is given by I (t) = bt2 - ct3 where b = 2.20 m/s and c = 0.120 m/s3 Calculate the average velocity of the car for the time interval t = 0 to t = 10.0 s Express your answer in meters per second.

EXECUTE t - 0: x = 0 t - 10.0 s: x - (2.20 m/s2) (10.0 s)2 - (0.120 m/s3) (10.0 s)3 - 220 m - 120 m = 100 m Ax 100 m Then Vav-I At 10.0 s = 10.0 m/s. Part B Calculate the instantaneous velocity of the car at t = 0. Express your answer in meters per second. v = 0 m/s Previous AnswersPart C A car is stopped at a traffic light. It then travels along a straight road so that its distance from the light is given by c (t) - bt2 - ct3 Calculate the instantaneous velocity of the car at t = 5.00 s. where b = 2.20 m/s and c = 0.120 m/s' Express your answer in meters per second.
