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} = at2 - pt', where a = 1.50m/S2 and p = 0.0500 m/s'. Calcn1ate the average velocity of the car for each time interval:
(a) t = 0 to t = 2.00 s;
(b) t = 0 to t = 4.00 s;
(c) t = 2.oo8tot = 4.008.
