4. A spring is hanging vertically with its bottom at a height of 1 m. We attach a 1 kg mass to the spring, and see that, after we gently lower it and let go, the bottom of the spring is at height of 0.95 m. Draw an energy interaction diagram starting at the moment the mass is attached and ending when the mass comes to rest. What is the value of the spring constant for this spring? Part 1:...

An ice cube of mass 500 g at 0 °C is dropped into an insulated container of 1.0 kg of water that initially is at room temperature (25 °C), and eventually the system reaches equilibrium. The insulator is not perfect, so 20 kJ of heat flows from the room into the water during the process. 3. a. Calculate the entropy increase in the ice that melts into water. b. Calculate the entropy loss of the water that cools down. c....

6) A mass-spring system consists of a 250-g mass hanging from a spring with a spring constant of k 0.18 J/m2. The mass is pulled down 7.1 cm from its equilibrium position and released from re a) How much work did the person do when she pulled the spring down from its equilibrium position? Assume that the mass was at rest before she pulled it down, and before it was released. (Use the energy-interaction model, not the expression W FavgAx,...

A massless spring with a spring constant k = 22.0 N/m is hanging vertically from the ceiling neither stretched nor compressed as shown in part (1). A 0.45-kg ball is attached to its free end, then slowly lowered to its equilibrium (E) position (2). Finally, the ball is pulled down a distance of 15.0 cm before being released (3). a) Using the provided information derive the algebraic expression for the stretched distance in the spring while at equilibrium. b) Calculate...
