How much heat energy is required to raise the temperature of 0.367 kg of copper from 23.0 c to 60.0 c ? the specific heat of copper is 0.0920 cal/(g x c)

if 125 cal of heat is applied to a 60.0 g - piece of copper at 23.0 c, what will the final temperature be? the specific heat of copper is 0.0920 cal /(g x c)

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.
