Question

Problem 10-1 Please consider a space launch from Kennedy space center at sea level to a target orbit at an altitude of 300 km. Please calculate the change (m/s') in the gravitational acceleration (g) between the launch pad and the target orbit Problem 10-2 A satellite with a mass of 5000 kg is thrown vertically upward with an initial velocity of 5,000 m/s. Starting with the governing equations m dV/dt--mg(i.e. negligible drag force) V dz/dt where V is the vertical velocity (m/s) of the satellite and z is the altitude (m), please calculate the the maximum altitude reached by the satellite. For simplicity neglect the variation in the gravitational acceleration (i.e. g = constant 9.81 m/s^2) Problem 10-3 Using EXCEL please calculate the maximum altitude of the satellite in the last problem if the drag force is zero and the gravitational acceleration is not constant and insteadg is given by
