PRELIMINARY QUESTIONS 1. One of the timing devices Galileo used was his pulse. Drop a rubber ball from a height of about 2 m and try to determine how many pulse beats elapsed before it hits the ground. What was the timing problem that Galileo encountered? 2. Now measure the time it takes for the rubber ball to fall 2 m, using a watch or clock with a second hand or seconds display. Did the results improve substantially? 3. Roll the hard ball down an incline that makes an angle of about 10° with the horizontal. First use your pulse and then your watch or clock to measure the time of descent. 4. Do you think that during Galileo's day it was possible to get useful data for any of these experiments? Why?

6. A train is moving with a constant speed. The train moves 60 meters for every 1.5 seconds that elapses. a. Assume that we get 40 by dividing 60 by 1.5. What is the name that is commonly given to a quantity represented by this number 40? b. To denote the quantity completely, what additional information must be given besides the number 40? c. How would you interpret the number 40 in this instance? Your answer should mention distance and time. d. Use your interpretation (not algebra) to find the distance the train moves in 2.5 seconds.

You measure the motion of a dynamics cart using a motion sensor. You then plot the cart’s position vs. time and velocity vs. time. The best way of finding the average acceleration of the cart is to find: a. the y-intercept of the position vs. time plot. b. the y-intercept of the velocity vs. time plot. c. the slope of the position vs. time plot d. the slope of the velocity vs. time plot. e. none of the above
The activity: Fold the sheets of bond paper length-wise and tape them on the floor to make a track for the toy car. Make the track long enough for the toy car to travel 100 cm. Flick or push the toy car with you finger to send it moving along the track and measure the timeit takes to travel 100 cm. In the first activity, does it matter if the floor where you made the track for the toy car is level or not? a . No, because in the activity, the speed of the toy car is constant. b . Yes, because if the floor was not level, gravity would have an influence on the motion of the toy car. c . No, because the activity is looking at the relationship between total distance traveled and elapse time. d . No, because the motion of the toy car will only depend on the flick or push strength that was used
< Question 9 of 20 Bob has just finished climbing a sheer cliff above a beach and wants to figure out how high he climbed. All he has to use, however, is a baseball, a stopwatch, and a friend on the ground with a long measuring tape. Bob is a pitcher, and knows that the fastest he can throw the ball is to = 91.0 mph. Bob starts the stopwatch as he throws the ball (with no way to measure the ball's initial trajectory) and watches carefully. The ball rises and then falls, and after f₁ = 0.910 s, the ball is once again level with Bob. Bob cannot see well enough to time when the ball hits the ground. Bob's friend then measures that the ball landed a distance of x = 332 ft from the base of the cliff. How high up is Bob if the ball started from exactly 5 ft above the edge of the cliff? height of the cliff: 5 fi TOOLS x10
