a bat is thrown straight up in the air. which of these statements about it's kinetic energy is true.
the ball has the least kinetic energy at the top of it's flight.
the ball has the most kinetic energy halfway to the top of it's flight.
the ball has the least kinetic energy at the start of it's flight.
the ball has the most kinetic energy at the end of it's flight. (before it gets caught)

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
