A basketball player dribbles the ball while running at a constant speed straight across the court. Think about the velocity and acceleration of the ball and then sketch a motion diagram for the ball. Explain how you arrived at your sketch.
Consider Concept Map 1,1, which provides an overview of motion. Review Sections 1,2 and 1,3 and make a list of at least five additional concepts you could add to the map. Now consider where to place these concepts on the map. Keep in mind that general, more inclusive concepts go towards the top, whereas more specific ideas and examples go toward the bottom. Place your concepts on the map. Draw the possible connections between your five new concepts and the rest of the map. Remember to use "linking words'' to create propositions and to express your ideas clearly. When you've finished updating your map, compare your revised concept map with that of a classmate's. Are they identical? Would you expect them to be?
Case Study Crall and Whipple attached a fan to a cart placed on a level track and then released the cart. They made a position-versus-time graph (Fig. P2.54) and fit a curve to these data such that x=0.036m+(0.0080m/s)t+(0.10m/s2)t2 a. Find and graph the velocity as a function of time. b. What is the shape of the velocity-versus-time graph? What do you expect the acceleration-versus-time graph to look like? Explain. c. Find and graph the acceleration as a function of time.
Acceleration may result from what? (2.3) (a) an increase in speed (b) a decrease in speed (c) a change in direction (d) all of the preceding
A fireworks shell is accelerated from rest to a velocity of 65.0 m/s over a distance of 0.250 m. (a) How long did the acceleration last? (b) Calculate the acceleration.
A student drives a moped along a straight road as described by the velocity-versus-time graph in Figure P2.12. Sketch this graph in the middle of a sheet of graph paper. (a) Directly above your graph, sketch a graph of the position versus time, aligning the time coordinates of the two graphs. (b) Sketch a graph of the acceleration versus time directly below the velocity-versus-time graph, again aligning the time coordinates. On each graph, show the numerical values of x and ax for all points of inflection. (c) What is the acceleration at t = 6.00 s? (d) Find the position (relative to the starting point) at t = 6.00 s. (e) What is the mopeds final position at t = 9.00 s? Figure P2.12
You slam on the gas of your racecar and you accelerate at 12 m/s2 from rest to a final velocity of 48 m/s How far will you travel during this acceleration. There IS enough information to find the answer, use your tools.
A blue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.9m/s2. A green car arrives at the position of the stop-light 4s after the light turned green. What is the slowest constant speed which the green car can maintain and still catch up to the blue car in m/s?
Lesson: Reaction Time What role does reaction time play in applying the brakes to a car in an emergency situation? Estimate the distance a car travels at 100 km/h during your reaction time in braking. How did you use reaction time in the recent disaster you experienced with the typhoon Odette? Give examples for which reaction time is important in sports.
