(i) a particle moves in a plane under a force directed towards a fixed point s whose coordinates referred to rectangular 8. (a, 0). the particle passes through the origin 0 axes are and through the point p(a, 2a). the velocity at o is uj; the velocity at p is in the direction of the vector ij. use the principle of conservation of moment of momentum to find the speed at p

The path of a satellite orbiting the earth causes it to pass directly over two tracking stations a and b, which are 51 miles apart. when the satellite is on one side of the two stations, the angles of elevation at a and b are measured to be 87 degrees and 84 degrees, respectively. (a) how far is the satellite from station a? (b) how high is the satellite above the ground?
