An iceboat has a constant velocity toward the east when a sudden gust of wind causes the iceboat to have a constant acceleration toward the east for a period of 3.0 s. A plot of x versus t is shown in Fig. 2-47, where t = 0 is taken to be the instant the wind starts to blow and the positive x axis is toward the east.

(a) What is the acceleration of the iceboat during the 3.0 s interval?

(b) What is the velocity of the iceboat at the end of the 3.0 s interval?

(c) If the acceleration remains constant for an additional 3.0 s, how far does the iceboat travel during this second 3.0 s interval?
