Open Question: Kinetic energy?!? Please help.?
A baseball outfielder throws a .150kg baseball at a speed of 40.0m/s and an intial angle of 30 deg. What is the kinetic energy of the baseball at the highest point of its trajectory?

wave plane
As the kinetic part of the energy goes up with the square of the speed of the water, a small increase of speed gives a relatively large increase of kinetic energy." ---- Classification of wave energy devices based on function is an
The Kobold turbine within the archimedes bridge
Kobold is able to convert kinetic energy from marine currents into mechanical rotor energy with a high rendering. The Kobold turbine is a rotor mounted on a vertical shaft which produces mechanical energy by exploiting marine currents.
