A brick mason is on a steep roof repairing a chimney and drops a brick. If the brick slides down the roof and leaves the edge of the roof with the velocity v = (3.00 m/s)î − [(5.00 m/s) + (9.80 m/s2)t]ĵ, determine the displacement of the brick from the edge of the roof at a time t = 0.315 s after it leaves the edge of the roof.

Which is the best for showing percentages of different types of cars sold(gas hybrid , electric , other ) in the united states ?

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
