An object has a velocity of 3 m/s south. A 4 newton force is applied east, a 3 newton force is applied north, a 4 newton force is applied
west, and a 3 newton force is applied south. What will the velocity
of the object be in 30 seconds time?

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)

Aria drove to the store, did some shopping, and then came home. during maria's trip, when was her displacement equal to zero?

Panel bc in fig. p2.76 is semi-circular, with the 3 meter radius and horizontal straight edge through point b. compute (a) the hydrostatic force of the water on the panel, (b) its center of pressure, and (c) the moment of this force about point b. assume atmospheric pressure on the dry side of the panel
