Three people are standing on a horizontally rotating platform in an amusement park. one person is almost at the edge, the second one is (3/5)r from the center, and the third is (1/2)r from the center.

1-if the period of rotation of the first person is t1 = t, find in terms of tthe period of rotation of the second person.

2- if the period of rotation of the first person is t1 = t, find in terms of t the period of rotation of the third person.

3-if the speed of the first person is v1 = v find in terms of v the speed of the second person

4- if the speed of the first person is v1 = v find in terms of v the speed of the third person.

5- if the radial acceleration of the first person is a1 = a, find in terms of athe radial acceleration of the second person.

6- if the radial acceleration of the first person is a1 = a, find in terms of athe radial acceleration of the third person.
