Let us take the uncertainty in 02,final to be +0.50. Using this and the uncertainty in the speed from question 6, what is then the uncertainty in the X compoment of the velocity, in cm/s? (This is the process we learned in lab FV - Forces and Vectors. You can review the minilecture on propagation of uncertainty that was part of Prelab FV.) Enter your answer with one significant figure.In our experimental setup, the frequency of the spark generator is very steady. This means that the uncertainty associated with the time intervals between consecutive marks introduces a negligible contribution to the total error, so we do not need to worry about this. However, we will measure distances with a cheap plastic ruler, and that imposes limitations to the precision of the measurement. A safe estimation of the uncertainty to our measurement of the distance between points X and Y due to the precision of the ruler is 10.1 cm (both due to the cheap construction of the measuring tool and due to reading errors). As discussed in previous labs, this uncertainty needs to be propagated through calculations. 6. What is the uncertainty in the speed of puck 2 after the collision, in cm/s? Round up your result to two significant figures
