Question

(A) The mass of the object, because it is required to determine the force due to gravity exerted on the object, and the velocity of the object the instant before it reaches Earth’s surface, because it is required to determine the change in velocity of the object.

(B) The mass of the object, because it is required to determine the force due to gravity exerted on the object, and the distance fallen by the object, because the force is exerted during the entire falling distance.

(C) The velocity of the object the instant before it reaches Earth’s surface, because it is required to determine the change in velocity of the object, and the acceleration of the object, because it is required to determine the force due to gravity exerted on the object.

(D) The distance fallen by the object, because the force is exerted during the entire falling distance, and the acceleration of the object, because it is required to determine the force due to gravity exerted on the object.

A 70 kg space voyager is stranded on a 700 kg escape pod that has left the main spacecraft and is floating in free space (you may assume its velocity is 0 m/s). A rescue ship is approaching and will pass within 100 m of the escape pod. The space voyager plans to push herself away from the escape pod towards the point by which the rescue ship will pass (point P in the diagram). The space voyager knows that she can apply a constant force of 100 N while she pushes for the 0.50 s it takes her to straighten her arms. (a) What will her velocity be after she has finished pushing against the rescue pod? (b) How long before the rescue ship is due to arrive a point P should the space voyager begin her push?

Your answer is partially correct. Docking a Spaceship. You and your crew must dock your 2.75 x 104 kg spaceship at Spaceport Alpha, which is orbiting Mars. In the process, Alpha's control tower has requested that you ram another vessel, a freight ship of mass 1.80 × 104 kg, latch onto it, and use your combined momentum to bring it into dock. The freight ship is not moving with respect to the colossal Spaceport Alpha, which has a mass of 1.85 x 107 kg. Alpha's automated system that guides incoming spacecraft into dock requires that the incoming speed is less than 2.0 m/s. (a) Assuming a perfectly linear alignment of your ship's velocity vector with the freight ship (which is stationary with respect to Alpha) and Alpha's docking port, what must be your ship's speed (before colliding with the freight ship) in order that the combination of the freight ship and your ship arrive at Alpha's docking port with a speed of 1.65 m/s? (b) What will be the velocity of Spaceport Alpha when the…
