1. A mars lander may use small rockets to carry cameras on parachutes to a high altitude to survey the surrounding areas to identify interesting places for the rover to explore. For these rockets the payload mass, Mt, is 2 kg, the rocket structure mass, Ms, is 1 kg. The solid propellant rocket has a specific impulse, Isp, of 150 s, a burn time, to, of 20 seconds, and a propellant mass of 0.75 kg. Assume that there is negligible drag and that the rockets ascend vertically. What are: 1) the burn-out velocity, ub 2) the burn-out altitude, hs 3) the maximum altitude, hmax Hmars = 4.469 x 10* km3/s², Rmars = 3397 km, gmars = 3.63 m/s2 %3D
