Phase 1} To leave the Earth, the rocket that will carry the astronauts must reach an escape velocity of 40,000 kmih. Assume that the mass of the rocket + fuel is 64000 kg, calculate the force (in Newtons) the engine must provide to accelerate the rocket from rest to escape velocity in a 5.0 minute period of time. (2 marks) Phase 2) As the spacecraft approaches Mars, it will begin to feel the gravitational pull of the planet. The spacecraft needs to re its engines to slow down when it reaches a distance where the gravitational eld strength equals 1.75 Njkg. Calculate the distance away from the surface of Mars where the spacecraft will experience this gravitational field strength. Assume the mass of Mars is 6.39 x 1023 kg, and its radius is 3,390 km. (1 mark) Phase 3} In order to safely land on Mars, the astronauts must slow down very quickly. During the descent, the spacecraft fires a rocket which provides upwards thrust. Astronauts experience an upwards acceleration of 20 mfsz. Remember, the astronauts are also experiencing the surface-gravity of Mars at the same time. If the spacecraft has a mass of 12 000 kg, what is the force that the rocket provides in order to slow down the spacecraft.
