The largest land predator is the male polar bear, which typically has a mass of around 5.00 × 102 kg. If the maximum kinetic energy for a polar bear with this
mass is 6.05 × 104 J, what is its top speed?

Ms.hidalgo opens the door to her classroom. her classroom is 60 degrees and the air outside is 80. predict what will happen using your knowledge of how heat flows.

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

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?
