Alarge fake cookie sliding on a horizontal surface is attached to one end of a horizontal spring with spring constant k = 440 n/m; the other end of the spring is fixed in place. the cookie has a kinetic energy of 20.0 j as it passes through the spring's equilibrium position. as the cookie slides, a frictional force of magnitude 11.0 n acts on it. (a) how far will the cookie slide from the equilibrium position before coming momentarily to rest? (b) what will be the kinetic energy of the cookie as it slides back through the equilibrium position?

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix. b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds. c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer. d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)
