Apotter's wheel, with rotational inertia 46 kg · m2, is spinning freely at 40 rpm. the potter drops a lump of clay onto the wheel, where it sticks a distance 1.2 m from the rotational axis. if the subsequent angular speed of the wheel and clay is 32 rpm what is the mass of the clay?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?
