Mario's velocity vector relative to the ice is
(note that all velocities mentioned here are given in m/s)
The puck is moving in a direction of 17.8 degrees west of south, or 252.2 degrees counterclockwise relative to east. Its velocity vector relative to the ice is then
The velocity of the puch relative to Mario is
Then, relative to Mario,
a. the puck is traveling at a speed of 
, and
b. is moving in a direction 
such that
which is about 
west of south.
I have tried to answer this inverse square Coulomb's law question more fully, but have been blocked from doing so. I do not know why.
Answer:
When a non-metal burns in oxygen, a non-metal oxide forms as product. Here is the word ... Coal is a form of carbon and when it burns in oxygen we can represent the reaction with the following word equation: carbon + ... Which non-metal do you think reacts with oxygen to form sulfur dioxide? See if you ... C + O2 → CO2.
