Question

Select True or False to each of the following statements about this week's elastic collision experiment. In order to receive credit for this question you must answer ALL statements correctly.
True False  Most of the Excel formulas are pre-programmed for your use, including the direction each cart is moving after the collision with the applicable sign(+ or -).
True False  Set the photogates to PULSE mode and the memory switch set to ON.
True False  In trials 3 and 4, Cart 1 will transfer all of its momentum to Cart 2. To approximate a final velocity of zero, the lab manual suggests using a large time of at least 10 seconds.
True False  After the first cart passes through the first photogate, you must memorize the first time that appears on the photogate and reset the timer before either cart passes through another photogate.
True False  Move the carts along the air track prior to turning on the air to prepare for each experimental run.
