Concept explainers
Problems 39 through 45 are motion problems similar to those you will learn to solve in Chapter 2. For now, simply interpret the problem by drawing a motion diagram showing the object's position and its velocity vectors. Do not solve these problems or do any mathematics.

- Direction: Solve what is required in each of the following problems. Show a step by step process in finding the solution of the problem. An airplane accelerates down a runway at 3.20 m/s2 for 38 s until is finally lifts off the ground. Determine the distance traveled before takeoff. Upton Chuck is riding the Giant Drop at Great America. If Upton free falls for 2.80 seconds, what will be his final velocity and how far will he fall? A car begins driving from a stationary position. It accelerates at 5 m/s2 for 15 seconds, then travels at a steady speed for another 10 seconds, all in the same direction. How much distance has it covered since it started driving?arrow_forward1. Is it possible that the magnitude of the speed is also the magnitude of the velocity? Explain your answer. 2. A man walked from point A to F following the route in the grid below in 250 seconds.

Choose all that apply. (HINT: The statements that are false should contradict themselves or a definition.) 1. An object can simultaneously be moving and have zero velocity. 2. An object can simultaneously have zero velocity and have constant position. 3. An object can simultaneously have positive velocity and have constant acceleration. 4. An object can simultaneously have positive displacement and be traveling a positive distance. 5. An object can simultaneously be traveling a negative distance and have constant positive acceleration. 6. An object can simultaneously have positive acceleration and have positive velocity.arrow_forward
