Newton's Cradle is a device that demonstrates the concept of conservation of motion. If there was no air resistance on earth, the balls on the end of the line would keep going back and forth forever. Since we have air resistance on earth the device will eventually come to a stop.
A student decides to see how many hits it would take in order for the device to stop moving.
The student records the first hit having a height as being 20 cm. The student records the second hit having a height as being 19.6 cm. The student records the third hit having a height as being 19.2 cm.
How many hits would it take for the balls to stop moving? SHOW ALL WORK!!!

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
