A 3.10 kg penguin runs onto a huge sheet of frictionless ice. At t = 0 s it is at x = 0 m and y = 0 m with an initial speed of 0.330 m/s along the positive x-axis. It slides while being pushed by the wind with a force of 0.350 N directed along the positive y-axis. Calculate the penguin's speed at t = 7.22 s.
