Question

Two hockey players scratch perpendicular x and y axes into the ice. Player 1 hits a puck so that it travels in the x-axis direction with constant velocity of magnitude v. Thereafter Player 2 strikes the puck with his stick so that it travels in the positive y-axis direction with constant velocity of magnitude v. The force which player 2's stick exerted on the puck was directed along:

Before the strike the puck has velocity $v$ along $+ x$ ; after, $v$ along $+ y$ . The force is along the change of momentum $Δ p = m v (\hat{j} - \hat{i})$ .

This points 45 degrees from the negative x axis and 45 degrees from the positive y axis.
