this question is referring to a physics lab on two dimensional kinematics where we had a slope and a cart that was released from the top. 1. explain why using a small slope (<10) is preferred to using a steeper slope. Explain the reasons other than the obvious "so that the cart doesn't crash too hard". What is it about a gentler slope that may improve your data collection? 2. are the numbers 9.62+/- 0.01 and 9.69+/- 0.02 in agreement? show work. 3. are the numbers 2.62+/- 1.63 and 4.91+/- 0.70 in agreement? show work. 4. compare the two scenarios in questions two and three. In which case are the values themselves (without considering the uncertainties) closer? is that also the one that demonstrated better agreement? Why do you expect I intend for you to take away from this particular investigation
