Suppose you like to listen to two different radio stations. the opera station broadcasts at 90.5 mhz and the rock and roll station broadcasts at 107.0 mh. s. which station's signal has waves with longer wavelenghts and which stations signal has station has waves with higher energy?

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.
