This typeof graph is usually referred to as an x vs. t graph. To draw such a graph, choosean axis system in which timet is plotted on the horizontal axis and position x onthe vertical axis. Then, indicate the values of x at various times t. Mathematically,this corresponds to plotting the variable x as a function of t. An example of agraph of position as a function of time for a particle traveling along a straight lineis shown below.

Inthis graph, time t is plotted on the horizontal axis and velocity v on the verticalaxis. Note that by definition, velocity and acceleration are vector quantities. Instraight-line motion, however, these vectors have only one nonzero component inthe direction of motion. Thus, in this problem, we will call v the velocity and a theacceleration, even though they are really the components of the velocity andacceleration vectors in the direction of motion.Part DWhich of the graphs shown is the correct v vs. t plot for the motion describedin the previous parts?Av (m/s)v (m/s)0.80.80.60.60.40.40.20.2t (s)10 20 30 40 50t (s)10 20 30 40 50CDv (m/s)v (m/s)0.80.80.60.60.40.40.20.2(s)10 20 30 40 50(s)10 20 30 40 50• View Available Hint(s)CranhPearsonCopyright © 2021 Pearson Education Inc.

A student writes, "A bird that is diving for prey has a speed of -10 m / s." What is wrong with the student's statement? What has the student actually described? Explain.
Land west of the San Andreas fault in southern California is moving at an average velocity of about 6 cm/y northwest relative to land east of the fault. Los Angeles is west of the fault and may thus someday be at the same latitude as San Francisco, which is east of the fault. How far in the future will this occur if the displacement to be made is 590 km northwest, assuming the motion remains constant?
A hard rubber ball, released at chest height, falls to the pavement and bounces back to nearly the same height. When it is in contact with the pavement, the lower side of the ball is temporarily flattened. Suppose the maximum depth of the dent is on the order of 1 cm. Find the order of magnitude of the maximum acceleration of the ball while it is in contact with the pavement. State your assumptions, the quantities you estimate, and the values you estimate for them.
Two canoeists in identical canoes exert the same effort paddling and hence maintain the same speed relative to the water. One paddles directly upstream (and moves upstream), whereas the other paddles directly downstream. With downstream as the positive direction, an observer on shore determines the velocities of the two canoes to be 1.2 m/s and + 2.9 m/s, respectively, (a) What is the speed of the water relative to the shore? (b) What is the speed of each canoe relative to the water?

Sue applies her brakes but can accelerate only at 2.00 m/s2 because the road is wet. Will there be a collision? State how you decide. If yes, determine how far into the tunnel and at what time the collision occurs. If no, determine the distance of closest approach between Sues car and the van.
