13 In this question, i and j are horizontal unit vectors in the East and North directions respectively. Ice hockey is played with a rubber disc called a puck. At the start of one ice hockey match, Marta hits the puck from the point with position vector (30i +13j) m. The puck is modelled as a particle which slides horizontally on a level surface at a constant velocity of (-4i+ 6j) ms For the puck to have a constant velocity,...

Hi, for the first question, I would like to know why the CN
group and Methyl group are both pointing out of the plane? How do I
look in order to be able to get the same answer? For the second
question, how do I know which one will point out of the plane and
which one will go into the plane?
