Second Law Lab. Remember to check your equations with me before you start the data collection. Secondly, make sure the cart is just before the first gate when you release the cart. The goal is to have an initial velocity of zero when the first gate timer is tripped.
When done, please show the data to me. I will check the numbers and your % error.
Finish the summary questions individually.
