the attached file is an old exam my professor sent out. i my struggles were with 2 and 3.(adsbygoogle = window.adsbygoogle || []).push({});

number 2:

I am having trouble calculating the moments and picking a vector for r in the equation M=r x F which reads the cross product of the r and F vectors. Also to find the thetas, for part 2, can I use the dot product to find the angle between them and thus theta?
