1. Neglecting air resistance, how fast will a wrench(m = 0.1 kg) be traveling when it hits the ground, if it's dropped from the top of NASA's SLS booster (98m high)?

2. Two asteroids pass by each other in the void of interplanetary space. Asteroid Alpha has a mass of 3 10⁶kg. Asteroid Echo has a mass of 5 10⁶ kg.

If the two are separated by 1000 m, what is the force of gravitational attraction between them? (in Newtons)

Canvas has not idea how to deal with units in a numeric problem so please just enter the numeric portion of your answer and we will assume it is in Newtons.

Example:suppose your answer is 12.345Newtons,just type "12.345" in the answer box

3. You are spinning a 0.25 kg mass over your head at the end of a 0.5 m string. If you let go of the string, the mass will sail off on a tangent at 2 m/s. What is the angular momentum of the spinning mass before release?

Because angular momentum is always conserved, where does the angular momentum go after release?

4. What are the origin, principal direction, and fundamental plane for the geocentric-equatorial coordinate system?

Origin:

Principal Direction:

Fundamental Plane:

5. For the same satellite (in Earth orbit with an altitude at perigee of 1000 km and an altitude at apogee of 2000 km)what it the eccentricity of its orbit?
