1. The maximum velocity of a mousetrap car is at
a. The very beginning of the car's movement
b a point along the car's journey where it looked as though it was covering most length per second
c. just before the car stopped
d. the same place as maximum acceleration
2. (multiple choice)
An alternative way to measure acceleration would be to mark the point where the car is at the end of each half second interval. This would allow you to see instantaneous changes in acceleration rather than just the average. Choose the ideas that you think would be useful in the calculations.
a. measure the distance between each mark.
b. Divide the change in distance from 1 segment to the next by half a second.
c. add together all the half seconds of time.
d. adding up all of the distances and dividing by the number of segments there are.
e. Divide the change in velocity from one segment to the next by half a second.
3. Put the steps in the correct order to measure a mouetrap car's deceleration. Measure the maximum velocity before any deceleration measurments.
a.Divide the change in velocity by time from Vmax to stop.
b.Measure the distance between Vmax point and stopped.
c. Measure the maximum velocity for 1 second prior to the Vmax point
d. Mark the point where you feel the car is beginning to slow from maximum velocity.
e. Mark the point where the car stops completely.
