PPH 0075 Reinforcement Question Chapter 2 1/5 ASD 2007/08 Reinforcement Question Chapter 2: Kinematics 1. Two cars, a Porsche and a Honda, are traveling in the same direction, although the Porsche is 186 m behind the Honda. The speed of the Porsche is 24.4 m/s and the speed of the Honda is 18.6 m/s. How much time does it take for the Porsche to catch the Honda? 2. a) The figure next shows the vertical velocity component of an elevator versus time. If the elevator starts to move at t = 0 s, when is the elevator at its highest location above the starting point ? b) How high is the elevator above the starting point, t = 0 s, after 20 s have elapsed? 3. The figure next shows a graph of speedometer readings obtained as a car comes to a stop along a straight-line path. How far does the car move between t = 0 and t = 16 s? 4. The figure below shows a graph of x ( t ) in meters, on the vertical axis, for an object traveling in a straight line. (a) What is for the interval from t = 0 to t = 4.0 s? (b) What is for the interval from t = 0 to t = 5.0 s? (c) What is v x at t = 2.0 s?

PPH 0075 Reinforcement Question Chapter 2 2/5 ASD 2007/08 5. An object is moving along a straight line. The graph in the figure next shows its position from the starting point as a function of time. (a) In which section(s) of the graph does the object have the highest speed? (b) At which time(s) does the object reverse its direction of motion? (c) How far does the object move from t = 0 to t = 3 s? 6. A motor scooter travels east at a speed of 12 m/s. The driver then reverses direction
