Draw a compound that will give the spectoscopy data given below: Molecular formula: C5H9NO
IR(cm-1): 1670 cm-1; 3250 cm-1 (broad, mild intensity)
1H NMR: delta ppm (1,m); 7.55(1,s); 3.3(2,dt); 2.4(2,t); 1.9(2,tt), 1.7(2,tt)

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.
