A point at a distance of r from the center of a giant wheel speeds up with a tangential acceleration a. A point at
a distance of 3r from the center of a toy wheel has a tangential acceleration of 5a.
How does the angular acceleration of the giant wheel giant compare with the toy wheel Otoy?

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.  

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
