Example 2

A rightward force of 46.8 N is applied

to a 4.0-kg object. There is 14.8 N of

friction. Determine the acceleration.

F = 39.2 N

What is the acceleration of the object?

(Remember a = Fnet/m and acceleration needs a

direction)

F.

46.8 N

14.8 N

8 m/s/

Solution:

С C

0.125 m/s/s to the right

= 39.2 N

8 m/s/s to the left

8 m/s/s to the right

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
