A 1.0 kg ball is thrown into the air with an intial velocity of 30. m/s. A. how much Kinetic energy does the ball have?
B. How much potential energy does the ball have when it reaches the top of its ascent?
C. How high into the air did the ball travel?

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
