Amodel rocket with a mass of 0.181 kg is launched into the air with an initial speed of 92 m/s. how much kinetic energy will the rocket have at a height of 164 m? assume there is no wind resistance. 634 j 444 j 747 j 303 j

Will you chech and finish these for me, because i am stumped with them.

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.

This energy transformation diagram represents the energy of a skateboarder moving along a half-pipe. as she skates toward the top of the half-pipe, her original kinetic energy is converted to potential energy and friction. how much of the energy is potential?
