How does the freezing point of a given type of matter compare to the melting point of that same type of matter?                                                                                                       a)the freezing point is lower. b)they are both higher than the boiling point. c)the melting point is lower. d)they are the same.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
