. Answer only two of the following three questions 1 System consists of two particles with mass 2gm with positions and velocities as follows: r₁=i-2j-k r₂ = i + k v₁ = i- j + k v₂ = j + k Draw particles position and Find the kinetic energy of the system; and then compare it with the value of kinetic energy of the system center of mass. 2 A body of mass m was initially at rest. A constant force Fo acted on it for a time to ; then suddenly the force tripled to 3F. Find the total distance the body travels in a time 2to, and the net acceleration of this body. 3 An Atwood machine consists of two weights of mass 4kg and 8kg connected by a light inextensible cable of length 1m which passes over a pulley. Find the acceleration of the machine, discuss your result.

2 Center of Mass You have just finished a space walk where you were fixing your space telescope using a tool with a mass that is one tenth of yours. You realize you have no way to get back to your spaceship which is 10 meters away from you, so you throw the tool as hard as you can in the opposite direction of the spaceship which causes you to move toward the spaceship. Problem 2.1. When you finally reach the spaceship, how far away are you from the tool?
