Two wagons of equal mass are filled with an equal mass of bricks. person a pushes one wagon with twice the force that person b pushes the second wagon.

how is the acceleration affected?

a.
person a's wagon will accelerate at twice the rate of person b"s wagon.

b.
person a's wagon will accelerate at 1/2 the rate of person b's wagon.

c.
both wagons will accelerate at the same rate, since the mass is the same.

Aquarterback pedals 3.3meters southward and then run 5.7meters northward. whats the distance ? and whats the displacement?

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)
