Two cars are moving in the same direction in parallel lanes along a highway. At some instant, the velocity of car A exceeds the velocity of car B. Does this mean that the acceleration of A is greater than that of B? Explain.
Answer to relevant QuestionsIs it possible for the velocity and the acceleration of an object to have opposite signs? If not, state a proof. If so, give an example of such a situation and sketch a velocity–time graph to prove your point.A student at the top of a building of height h throws one ball upward with a speed of vi and then throws a second ball downward with the same initial speed, vi. How do the final velocities of the balls compare when they ...Explain the other geologically important type of chemical bonding, covalent bonding; give an example.Note the ionic radii and ionic charges of the eight most common ions in the earth’s crust in Table 2.1.
