Two satellites are in circular equatorial orbits of different altitudes. Satellite A is in a geosynchronous orbit (one with the same periodas the earth's rotation so that it "hovers" over the same spot on the equator). Satellite B has an orbit of radius rg = 34 000 km. Calculatethe velocity which A appears to have to an observer fixed in B when the elevation angle is (a) O and (b) 90°. The x-y axes are attachedto B, whose antenna always points toward the center of the earth (-y-direction).BAnswers:TB-N(a) 0=0: Vrel 3418.551(b) = 90°: Vrel = (i 1265.098¡ + i 6555.57j) km/hi+°j) km/h

A plane is moving horizontally at a constant speed of 1000 kilometers/hour and at a fixed height of 450 meters. The pilot then spotted the target below, and then launch a missile to hit a target on the ground. The question is (assuming that the target is exactly 450 meters below the plane), what is the angle that is needed for the missile to hit the target and the speed of the missile when it barely touches the target?
How would I begin to solve this problem? In Example 2.6, we considered a simple model for a rocket launched from the surface of the Earth. A better expression for a rocket's position measured from the center of the Earth is given by y(t) = (RE3/2 + 3*(g/2)1/2 REt)2/3 where RE is the radius of the Earth (6.38 ✕ 106 m) and g is the constant acceleration of an object in free fall near the Earth's surface (9.81 m/s2). (a) Derive expressions for vy(t) and ay(t). (Use the following as necessary: g, RE, and t. Do not substitute numerical values; use variables only.)
