Acoin is dropped from the top of a tall building. determine the coin's (a) velocity and (b) displacement after 1.5 sec.

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?

What’s #16 asking me and how do i solve it?

The energy produced as a result of this flow of electrons from atom to atom is called
