An object has a velocity of 10m/s and a mass of 1kg. After traveling some distance, the object now has a velocity of 100m/s and a mass of 1kg.

  1. What is the work being done on the object?

  2. Can you tell me what force made this?

  3. Can you tell me the distance traveled by the object

  4. What does it mean, that the object has kinetic energy equal to 5000 joules?

9. Object #1 has mass m; object #2 has mass 10m. They are separated by the distance d. We can conclude that: Object 1 exerts greater gravitational force on object 2, than object 2 exerts on 1. Object 1 exerts smaller gravitational force on object 2, than object 2 exerts on 1. Object 1 exerts on object 2 gravitational force equal in magnitude to force eqerted by 2 on 1. Our answer depends on distance d. 10. Consider two objects:...

Kinetic energy is the energy contained in an object because of its relative velocity to an observer. It is calculated quite easily as: E = 12 m v 2 where m is the mass (in kg); v is speed (in m/s) and E is the energy (in joules).

2 objects, moving in one dimension, undergo an isolated collision. Object 1 has initial velocity 1 m/s. Object 2 has an initial velocity -3 m/s. After the collision, the relative velocity of the 2 objects is vAB=+2 m/s. The reduced mass of the two objects is ⅔ kg. What is the change in total kinetic energy of the entire system during this collision?  Express your answer in units of Joules.
