USE THE STATEMENT AND FIGURE BELOW TO ANSWER THE NEXT TWO QUESTIONS (14 and 15). In a physics lab, your professor asked you to design an experiment that will produce the acceleration-versus-time graph as shown below. Q14a.png  Which of the following experiments will you perform to get the graph? Q14b.png

A woman exerts a constant horizontal force on a large box. As a result, the box moves across a horizontal floor at a constant speed “vo”. If the woman doubles the constant horizontal force that she exerts on the box to push it on the same horizontal floor, the box then moves:

Figure below shows the velocity of a train as a function of time. kinematics-graph.pngAt what time was its velocity greatest? During what periods, if any, was the velocity constant? During what periods, if any, was the acceleration constant? When was the magnitude of the acceleration greatest?

A projectile is fired from ground level with a speed of 150 m/s at an angle 30° above the horizontal on an airless planet where g = 10.0 m/s 2. What is the horizontal component of its velocity after 4.0 s? [Remember: The horizontal motion is a uniform motion.]
