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?

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
