Forms of Energy

Energy is described as the capability to accomplish a task, like the ability to push a block by applying force on it. It is a quantitative property that is used to accomplish work on an object.

Question

Thomas Bradshaw invented the first Merry-Go-Round to be operated by a steam engine. If the engine
suddenly stopped, and the Merry Go Round experienced no friction or air resistance, how could the riders
on the ride slow its rotational motion?
Run toward the edge of the platform.
Run toward the center of the platform.
Jump off the ride all at once.
Lay down flat on the platform.

The Wright Brothers designed an engine and propeller that would produce enough forward motion to lift a
simple light airplane. The 3 meter diameter blade rotated at a constant 330 rotations per minute (RPM).
How does the RPM of the tip of one blade compare to the RPM of the middle of the one blade (halfway
towards the center of the propeller)?
The RPM is twice as much.
The RMP is the same.
The RPM is half as much.
The RPM is one quarter as much.

Mechanical Engineering A turbine is running at rated power of 5 MW with the low speed shaft spinning at 12 RPM, with a wind speed of 10 m/s. The drive train has a polar moment of intertia of 50 million kg-m2. The wind suddenly increases in speed to 12 m/s for a 10 second period. What will be the speed of the rotor after that 10 second period, if no control changes are made to the turbine (i.e power delivered to the grid continues at 5MW, and no change in blade pitch angle, no change in Cp, etc.).
