Chapter 2, Problem 45P

& Two runners are running next to each other when one decides to speed up at constant acceleration a. The second runner notices the acceleration after a short time interval **#x2206;t when the distance between the runners is d. The second runner accelerates at the same acceleration. Represent their motions with a motion diagram and position-versus-time graph (both graph lines on the same set of axes). Use any of the representations to predict what will happen to the distance between the runners—will it stay d. increase. or decrease? Assume that the runners continue to have the same acceleration for the duration of the problem.

The distance between each mark on the scale is 14 meters and the time that passes between two consecutive pictures is 7 seconds. 1a. Which is the best description of boat's motion? -The boat is moving forward. -As time goes on, the position of the boat is increasing.     -The boat is moving in a positive direction at a constant speed. -The boat is moving at a constant speed. -This boat travels for the total time of 7 seconds and in that time it covers 14 meters. -The boat travels 14 meters every 7 seconds. -This is a red boat that moves to the right under the influence of air. -The position of the boat changes.   1b. What is the speed of this boat? (m/s) 1c. Where is this boat at t=4 sec? (m) 1d. Assuming the motion of this sailboat stays the same, where will it be at t=12 sec? (m)
1. Karlo is driving his padyak 15m/s when he noticed that he is approaching a stalled tricycle that is approximately 35m away. He steps on the breaks and the padyak stops 1.0m away from the stalled tricycle. At what rate did the padyak slow down? Assume that Karlo's reaction time is 2.0s. Reaction time is the time it takes a person to notice, think, and act in response to a given situation..
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.
