Parts (a), (b), and (c) of Figure 2.10 represent three graphs of the velocities of different objects moving in straight-line paths as functions of time. The possible accelerations of each object as functions of time are shown in parts (d), (c), and (f). Match each velocity vs. time graph with the acceleration vs. time graph that best describes the motion. Figure 2.10 (Quick Quiz 2.3) Match each velocity vs. time graph to its corresponding acceleration vs. time graph.
The following table gives the position s1t2 of an object moving along a line at time t. Determine the average velocities over the time intervals 31, 1.014, 31, 1.0014, and 31, 1.00014. Then make a conjecture about the value of the instantaneous velocity at t = 1.
Consider the following one-dimensional motions: (A) a ball thrown directly upward rises to a highest point and falls back into the thrower’s hand; (B) a race car starts from rest and speeds up to 100 m/s; and (C) a spacecraft drifts through space at constant velocity. Are there any points in the motion of these objects at which the instantaneous velocity has the same value as the average velocity over the entire motion? If so, identify the point(s).
For problem below, make use of the equation of motion of a vertically projected object: s=-1/2gt^2+v0t+s0,where s is the height of the object at time t seconds, g is 32 feet per second² and v0 and s0 are the initial velocity and initial height, respectively. Two friends are in competition. Each stands on the roof of the apartment building where each one lives. At the same time, each friend stands at the edge of the roof and throws up a basketball as hard as possible. Joan’s apartment building is 120 feet high, and she throws the basketball at a speed of 24 feet per second. Joe’s apartment building is 105 feet high, and he throws the basketball at a speed of 30 feet per second. d) When does the basketball hit the ground? Show your work and explain your answer. e) Write the function that describes the height of Joe’s basketball, in terms of time measured in seconds. f) Which basketball reaches a greater height? Show work and explain your answer. g) Is there a time when the basketballs…

A bowling ball travelling with a constant velocity hits the pins at the end of a bowling lane 68m long. The bowler hears the ball hitting the pins 4.36s after the ball is released from his hands. What is the velocity of the ball? (speed of sound is 343 m/s) Playing jackstone as a kid, you discovered that there is a certain time before the rubber ball falls and you took advantage of this when picking up the stars on the floor. If you threw the ball 48m/s up into the air, how fast will it be moving at a height of 26.72cm? How much time has elapsed upon reaching this height? A skydiver jumped out of a plane to shoot a skydiving scene for a certain spy movie. At what point in time should this spy-wannabe open his parachute when he is aware that the plane was at the altitude of 61m, and he needs to open it at a height of 366.49m?
A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 22.0 m/s.

The British Queen Elizabeth-class battleship HMS Warspite achieved the longest naval gunnery hit from a moving ship to a moving target in history, hitting the Italian battleship Guilio Cesare in the Battle of Taranto. According to known data, the range was 24000 meters, and that the British 15-inch Mk I naval gun has a maximum muzzle velocity of 800 meters per second. Due to movement, a headwind was against the British battleship, forcing its shells to decelerate by approximately 0.5 meters per second squared. Find the firing angle of the Warspite upon hitting Guilio Cesare. Find the impact velocity of the 15-inch naval cannon's shell.

Two cars travel at the same time from two point (A and B), which are 10km apart. It took the first car 20 minutes to travel from point A to B while it took 16 minutes for the other car to travel from point B to A. After how many minutes did the cars passed by each other if they travel at their respective uniform velocities.
Two rockets are fired upward. The first rocket’s velocity is given by the function v1(t)= 4t; the second rocket’s velocity is given by the functionv2(t)= 1/10t2. In both cases, t is in seconds and velocity is in feet per second. When the two rockets’ velocities are the same, how far ahead is the first rocket?
