Ideally, we would measure the initial launch speeds at a launch angle of 0o . However, the lower limit of the launchers is 20o . For this experimental setup, why is 0o the ideal launch angle to determine the initial speed

Let v1, v2, w be three linearly independent vectors in r 3 . that is, they do not all lie on the same plane. for each of the following (infinite) set of vectors, carefully sketch it in r 3 , and determine whether or not it is a vector space (i. e., a subspace of r 3 ). explain your reasoning

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.
