Question:

A rocket-powered hockey puck moves on a horizontal frictionless table. Figure EX4.9 shows graphs of v_x and v_y, the x- and y-components of the puck’s velocity. The puck starts at the origin.

a. In which direction is the puck moving at t = 2s? Give your answer as an angle from the x-axis.

b. How far from the origin is the puck at t = 5s?
