Iwill five 46 points. which statement below is true based on the graph? a) line segment ab is showing the cart traveling at 10 m/s. b) line segment cd is showing acceleration as the line has a straight increasing slope. c) line segment de is showing the cart is traveling at a constant rate. d) line segment bc is showing acceleration as the cart is increasing its speed.

Can somebody explain to me how newton's 3rd law relates to momentum? ~ap physics 1

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.

Aperson walks first at a constant speed of 4.89 m/s along a straight line from point a to point b and then back along the line from b to a at a constant speed of 2.95 m/s. what is the average speed over the entire trip?
