4) An asteroid orbiting the sun has a period of 3.81 years and an eccentricity of 0.286. Calculate its semi-major axis. (2 points) 5) An airplane operates using the premise of Bernoulli's theorem, higher velocity leads to lower pressure. For an airplane wing that has an area of 18.1 m², the velocity over the plane's wing is 82 m/s and under the wing it is 74 m/s. For an 1800 kg plane, what is the lift on the airplane wing (net vertical force)? You may assume the density of air is 1.2 kg/m³. (4 points)
