Stick Puck
two ice-hockey players simultaneously strike a puck with their sticks.the stick of one player exerts an eastwa?
exerts an eastward force on the puck of 12 N. the other player's stick exerts a northward force of 15 N on the puck. assuming that there is no frictional force between the puck and the ice, what is the magnitude of the net horizontal force on the puck?
I just answered this exact same question today. =)
You're dealing w/ vector addition. You have to draw a right triangle, with one side = 12 N east and one side = 15 N north. (Use common sense, if you don't know the order to draw them in, to determine that your hypotenuse should be heading north-east) Then, draw the hypotenuse and calculate the length of it, using the Pythagorean Theorem. c² = a² + b².
c² = 15² + 12² = 369
c = 19.2 N
I'm not sure if you need to calculate the direction, but if you do, use Tan θ = 15 / 12
θ = 51.3°
