Two cars start at the same time and travel in the same direction along a straight road. The figure below gives the velocity, v, of each car as a function of time, t. v (km/hr) Car A Car B t (hr) (a) Which car attains the larger maximum velocity, and how do you know? O A, because the area under its velocity curve is smaller. O A, because the peak of its velocity curve is higher. A, because its velocity curve hits zero first. O B, because the area under its velocity curve is larger. O B, because the peak of its velocity curve is lower. O B, because its velocity curve hits zero second. (b) Which car stops first, and how do you know? O A, because the area under its velocity curve is smaller. O A, because the peak of its velocity curve is higher. O A, because its velocity curve hits zero first. O B, because the area under its velocity curve is larger. B, because the peak of its velocity curve is lower. O B, because its velocity curve hits zero second. (c) Which car travels farther, and how…
