Consider a bicycle wheel that initially is not rotating. a block of mass m is attached to the wheel via a string and is allowed to fall a distance h. assume that the wheel has a moment of inertia i about its rotation axis.

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

How do we measure or think of speed in the united states?

Where do magnetic lines of force enter earth?
