Fifteen identical particles have various speeds: one has a speed of 2.00 m/s, two have speeds of 3.00 m/s, three have speeds of 5.00 m/s, four have speeds of 8.00 m/s, three have speeds of 9.00 m/s, and two have speeds of 14.0 m/s. (a) Find the average speed (in m/s). m/s (b) Find the rms speed (in m/s). m/s (c) Find the most probable speed of these particles (in m/s). m/s (d) What If? How many additional particles with a speed of 14.0 m/s must be added to the original fifteen particles for the average speed to become 10.0 m/s ? (Round your answer to at least the nearest integer.) particles (e) What would be the rms speed of the original plus additional particles (in m/s)? m/s

A 2-kg object, moving at 1 m/s, collides with a 1-kg object that is initially at rest. After the collision, the two objects are found to move away from each other at 1 m/s. Assume they form an isolated system. (a) What are their actual final velocities in the Earth reference frame? (b) What is the velocity of the center of mass of this system? Does it change as a result of the collision?
