Question
Answered step-by-step



1-   Suppose an object weighing 56,200 kg was moving through space at 29,500 km/hr. How fast would a 6,000 kg object on a direct collision course ( no deflection) need to be going to stop the first object with a resulting velocity of 0 km/hr ?

2-   A 5-ounce baseball is dropped from top of the Empire State Building. It is 1,250 feet to Fifth Avenue below. Neglecting air resistance, (a) how fast will the baseball be traveling when it hits the ground? (b) How long will it take for the baseball to hit the ground?

3-   Consider a motionless satellite weighing 250 kg in space (assume no gravitational influence). What will happen to the satellite if it fires a 2.5 kg object at a velocity of 11,200 m/s?

4-   A 165 g pellet is stuck to the outside edge of a spinning shaft with a diameter of 0.90 meters. The moment of inertia is 0.0156 kg·m2 and the angular velocity vector is 86 Radians per second. How fast will the rock be moving if it comes free?

5-   Using Newton's Law of Universal Gravitation, Calculate the average gravitational pull between the Venus and the Sun (Data found in Appendix D).

6-   What is the Potential Energy of a 11,550 kg satellite at an apogee altitude of 3,560 km?

7-   What is the Kinetic Energy of a 11,550 kg satellite traveling at a speed of 17,500 mi/hr?

8-   A satellite has an apogee altitude of 3,560 km and a perigee altitude of 460 km. (a) Calculate the satellite's semimajor axis. (b) Find the eccentricity of its orbit.

9-   Based on the information in Problem 8, (a) determine the altitude above the Earth of the orbit when the true anomaly is 65º. (b) What is the specific mechanical energy of this orbit?

10- Based on the information in question 8 and 9, What is the velocity of the orbit when the true anomaly is 65º?
