The students decide that additionally they want to test the toy company’s claim that the car’s speed is constant throughout the motion. How, if at all, does the experimental procedure from Part A need to be modified to verify that the car’s instantaneous speed is constant? Angela thinks they should use a motion sensor to collect speed vs. time data. If the graph of speed vs. time is horizontal with a zero slope, the instantaneous speed is constant. Blake thinks that they should use photogates positioned at the beginning and end of the 2-meter-long track to determine the instantaneous speed of the cart. The students measure the length of the cart and divide this length by the time recorded by the photogate to determine the instantaneous speed. Identify which student’s procedure will provide evidence for the claim that the instantaneous speed of the cart is constant. (Justify your response)
