A 2.2-kg block slides on a horizontal surface with a speed of v=0.80m/s and an
acceleration of magnitude a = 3.2m/s², as shown in (Figure 1).
Part A. What is the coefficient of kinetic friction between the block and the surface? Express your answer to two significant figures.
Part B. When the speed of the block slows to 0.40 m/s, is the magnitude of the acceleration greater than, less than, or equal to 3.2 m/s^2

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

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
