Calculate the moment of inertia of a bicycle wheel 66.7 cm in diameter. the rim and tire have a combined mass of 1.25 kg. the mass of the hub can be ignored since it distance from the axis of rotation is so small.

What is the most useful equation for electric power?

Can anybody me with this? ? (picture included.)

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
