A Honda Civic travels in a straight line along a road. Its distance x from a stop sign is given as a function of time t by the equation x(t)=t2t3, where = 1.60 m/s2 and = 0.0550 m/s3.

Express answers in meters per second.

a. Calculate the average velocity of the car for the time interval t=0 to t= 2.05 s.

b. Calculate the average velocity of the car for the time interval t=0 to t= 4.00 s.

c. Calculate the average velocity of the car for the time interval t=2.05 to t= 4.00 s.
