An astronaut is in an escape pocl that has been ejected from a spaceship and is moving at a constant velocity through deep space. The mass of the escape pod is much greater than the mass of the astronaut. a) 1What are the forces acting on the escape pocl'? Use Newton's laws to explain your answer. [2 marks] h} The astronaut exits the pod to capture some space junk. She gives the pod a gentle push to launch herself towards the space junk. Hera.r does the motion of the pod change due to the push, and how does this compare to the motion of the astronaut? Use Newton's laws to explain your answer. [3 marks] An 80 kg person sits on a sled of mass 8.0 kg. The sled is on a 25 degree slope and friction between the sled and snow is great enough that the sled will not slide without an external push. If the slope were any steeper, the sled would start to slide without needing a push. Take g = 10 m/s. a) Draw a diagram depicting the normal force, the gravitational force due to the combined mass of the sled and person, and the force due to friction. [2 marks] b) What is magnitude of the normal force? [1 mark] c) What is the magnitude of the frictional force? [1 mark] d) What is the coefficient of static friction? [1 mark]A person of mass 3!] kg puts their full weight on an injured leg. Assume the leg has mass l kg. a] 'What are the magnitudes of the force of the hip musole [EM] and the oontaot foroe at the hip {FH}? [3 marks] b] Consider another person of mass 9!] kg, also with a leg of mass 11'] kg. 1|Would the contact foroe at the hip be greater or smaller than for the person in part a}? Explain your answer using the equations you developed in part a]. [2 marks]
