6. A penguin is fired from a cannon at an initial height of 1.00 m above the ground. His initial velocity is 7.20m/s at 50° above the horizontal. The penguin later lands in a net positioned 1.00 m above the ground.a) Find the maxim height of the penguin above the ground during the flight.b) How far horizontally, Ax, is the net from the initial position?
