A 4.50 kg penguin runs onto a huge horizontal sheet of frictionless ice. The sheet lies on the xy-plane. At t = 0 s it is at x = 0 m and y = 0 m by an initial speed of 0.71 m/s along the positive x-axis. It slides while being pushed with the wind with a force of 0.45 N directed along the positive y-axis.

1. Compute the penguin's speed at t = 9.11s.

2. Compute the direction of his velocity at that time. Give the angle by respect to the x-axis.
