Katie conducted three trials of rolling a 5-kilogram ball down 10 steps at her school. Later, her class used the data she collected about the mass of the ball, the height of the stairs, and the gravitational constant to calculate the potential energy of the ball. The graph shows the students’ calculations for the ball at each step of the stairway.
a. Create a claim about how kinetic energy and potential energy can change as a ball rolls down a set of steps.
b. Describe the evidence that supports the claim from part (a).

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
