Four acrobats of mass 75.0 kg, 68.0 kg, 62.0 kg, and 55.0 kg form a human tower, with each acrobat standing on the shoulders of another acrobat. the 75.0-kg acrobat is at the bottom of the tower. (a) what is the normal force acting on the 75-kg acrobat? (b) if the area of each of the 75.0-kg acrobat’s shoes is 425 cm2 , what average pressure (not including atmo- spheric pressure) does the column of acrobats exert on the floor? (c) will the pressure be the same if a differ- ent acrobat is on the bottom?

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
