The teacher had already made a set of N = 25 measurements under the same conditions as the student and built the table below for the standard deviation of each component of linear moments, expressed in the same units (g cm/tq).
Consider the statments:
1) Taking into account the measurements of the student and the teacher, the momentum vector of particle 2 and its
uncertainty after the collision is:

2)The total momentum in the y direction, and its instrumental uncertainty, after the collision is (−4 ± 1) g cm/tq
