A hoop with a mass of 2.1 kg and a radius of 0.5 meters rolls (keeping its plane vertical) down an inclined plane descending a vertical distance of 1.0 meters. At the bottom, it rolls onto a horizontal surface. What are its translational and rotational kinetic energies on this surface? Neglect energy losses to friction.

Distinguish between a transverse wave and a longitudinal wave.

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
