1. how fast does an object need to travel to stay in orbit for one second?
2. how fast does an object need to travel to stay in orbit for two seconds?
3. how fast does an object need to travel to stay in orbit for three seconds?
4. you may have noticed that the object needs to keep going faster and faster to stay in orbit. what is the average acceleration needed for the object to stay in orbit from 1–3 seconds?
5. in the real world, orbiting objects such as satellites do not need to be constantly accelerating. what is different about real-world satellites and the theoretical satellites?

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
