Having aced your introductory physics course, you are hired as a summer intern at NASA. You are sent as part of a team to explore the possibility of mining iron from a small, airless spherical asteroid with a radius of 522 km and a surface acceleration of 2.7 m/sec2.

1)What is the mass of the asteroid?

2)What is the minimum vertical velocity you could give a 5 kg rock from the surface of this asteroid so that it continues to move upwards forever (i.e. it would never return to the surface)?

3)What is the minimum vertical velocity you could give a 10 kg rock from the surface of this asteroid so that it continues to move upwards forever (i.e. it would never return to the surface)

4)How far will the 5 kg rock go if it leaves the asteroids surface with a vertical velocity of 1000 m/sec?";

5)What will the speed of the 10 kg rock be at the surface of the asteroid if it is dropped from a point 1000km above the surface of the asteroid?

Consider the following scenario. You find yourself having some books with a total mass of 32 kg that you have to move from your bedroom to the door of your apartment using a rope attached to the crate. The coefficient of static friction between the crate and the floor is 0.65, and the coefficient of kinetic friction is 0.45 . (a) Pulling the rope horizontally, what is the minimum force you have to pull with to get the crate to...

1. Physics and astronomy student club has a recently established tradition of pumpkin drop, from the top of Wick Science Building to the "moat" below street level. Although the "experimental data" have not been made public, there have been rumors of the drop took 2.07 seconds, i.e. falling from rest with negligible air drag. Based on the rumor, how tall is the building from the "moat" to the roof? Ignore air drag or any rotation of pumpkins. Hint: You may...
