1. Question of the Day How can you determine the speed of an object using the CPO timer? Fully explain in detail. (Hint: There are 3 ways)

2. Revisit You can attach both A and B photogates to the timer, turn on the timer and push the yellow button on the bottom until interval is lit. Next, turn on both A and B lights. Then, send the object through photogate A and then photogate B. Measure the distance between the two photogates. Finally, divide the distance between the two photogates by the time that is shown on the CPO timer. This will determine the average speed of the object over that distance.

3. You can attach both A and B photogates to the timer, turn on the timer and push the yellow button on the bottom until interval is lit. Next, turn on the A light. Then, send the object through photogate A. Measure the distance/width of the object you put through the photogate. Finally, divide the distance/width of the object by the time that is shown on the CPO timer. This will determine the instantaneous speed of the object as it goes through that photogate.

4. Do the same thing as the second way except have B light lit. This will determine the instantaneous speed of the object as it goes through that photogate.
