9. If a passenger vehicle travels in a circular path at too high a speed, it can tip over. The image below shows a vehicle beginning to tip over. A group of students investigated the speed at which a passenger vehicle will begin to tip over by using a remote- control toy car. The students drove the car around circular paths of various known radii, at such a speed that it was just starting to tip for each radius. They timed the period of the cars motion and used the period to calculate the 'tipping speed' (the speed at which the toy car begins to tip over) of the car. The graph below shows the data collected by the students: Speed at which toy car begins to tip over (m s'¹') 14 12 10 8 TESTO 0 2 3 Radius (m) 5 6 7 Page 11
If you were performing this experiment in an in-class laboratory, you would be given one or more small iron balls. These would be utilized with a variant of the Free-Fall apparatus shown in the graphic below. (INSERT PICTURE HERE) You would first raise the upper black clamp to the desired height above the middle clamp. Then you would place the ball firmly in the upper clamp. Next, you would turn on the timer and adjust its initial reading to zero. After you release the ball, it falls towards the middle clamp. When it encounters this clamp, the timer stops and you can read the time of fall. Results are usually within 10% of the standard value of g. Here, in this online version, I will supply values of height (h) and time (t). First, calculate the average time (tav) for each height and use it as described next. You will use the third equation above to calculate the value of gravitational acceleration (g) in each case. Then, you will determine the…
