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.
