Question 3 a. A space craft achieved a maximum speed of 125,000 km/h on its way to photograph Mars. Beyond what distance from the Sun is this speed sufficient to escape the solar system? b. Consider a large massive spherical shell object. With all of its mass M is distributed at its radius R (shown in the figure). Draw a schematic greoh of gravitational force and corresponding Page 1 of 2 gravitational potential energy experienced by another object m at a distance r, where the distance varies as, r → 0 tor o. Figure 2: Question 3(b) Two masses system
