CONCEPTUA Physics PRACTICE PAGE Chapter 3 Linear Motion Free Fall Speed 1. Aunt Minnie gives you $10 per second for 4 seconds. How much money do you have after 4 seconds? 2. A ball dropped from rest picks up speed at 10 m/s per second. After it falls for 4 seconds, how fast is it going? 3. You have $20, and Uncle Harry gives you $10 each second for 3 seconds. How much money do you have after 3 seconds? 4. A ball is thrown straight down with an initial speed of 20 m/s. After 3 seconds, how fast is it going? 5. You have $50, and you pay Aunt Minnie $10/second. When will your money run out? 6. You shoot an arrow straight up at 50 m/s. When will it run out of speed? 7. So what will be the arrow's speed 5 seconds after you shoot it? 8. What will its speed be 6 seconds after you shoot it? Speed after 7 seconds? Free Fall Distance 1. Speed is one thing; distance is another. How high is the arrow when you shoot up at 50 m/s when it runs out of speed? 2. How high will the arrow be 7 seconds after being shot up at 50 m/s? 3.a. Aunt Minnie drops a penny into a wishing well, and it falls for 3 seconds before hitting the water. How fast is it going when it hits? b. What is the penny's average speed during its 3-second drop? Fram Rest, Ualot d-5t c. How far down is the water surface? 4. Aunt Minnie didn't get her wish, so she goes to a deeper wishing well and throws a penny straight down into it at 10 m/s. How far does this penny go in 3 seconds? 1063 Distinguish between " how fast," how for," and " how long "! 2 THEN diit -サ

CONCEPTUAL PhySics PRACTICE PAGE Chapter 3 Linear Motion Acceleration of Free Fall ls A rock dropped from the top of a cliff picks up speed as it falls. Pretend that a speedometer and odometer are attached to the rock to indicate readings of speed and distance at 1-second intervals. Both speed and distance are zero at time = zero (see sketch). Note that after falling 1 second, the speed reading is 10 m/s and the distance fallen is 5 m. The readings of succeeding seconds of fall are not shown and are left for you to complete. So draw the position of the speedometer pointer and write in the correct odometer reading for each time. Use g = 10 m/s? and neglect air resistance COO t= 0s m/s t= 1s m/s t = 2s YOU NEED TO KNOW: Instantaneous speed of fall from rest: V : gł m/s Distance fallen from rest: d= Voveroget t=3 s or d: '/29t 1. The speedometer reading increases the same amount, m/s, each second. m/s This increase in speed per second is called t= 4 s 2. The distance fallen increases as the square of the m/s 3. If It takes 7 seconds to reach the ground, t = 5 s then its speed at impact is m/s, the total distance fallen is m, and its acceleration of tall just before impact is m/s. m/s?. t= 6 s Hewitt 8 Goocoo
