Question

In the World Pond Hockey tournament held in Plaster Rock, NB, a puck on the ice travels 20.0 m [25° W of N], gets deflected, and travels 30.0 m [35° N of W]. Determine where the puck will end up with respect to its starting point, e.g., the puck's total displacement, using the three different methods discussed.

Hi, thank you for posting your question here at Brainly.

Basically, the problem asks you to find the resultant (R) vector quantity, which is the displacement. Illustrate the problem. Then, find the missing angles. In this case, the angle opposite to R is 150 degrees. Then, using the cosine law:

$R^{2} = 30^{2} +20^{2} -2(30)(20)(cos150)$
R = 48.36 m
