Angular Velocity disk
w = 10 * 2* 3.14 / (2* 60) = 0.523 rad/s
a)
Acceleration experienced by sister
As = r w^2 = 1.5* 0.523^2 = 0.41 m/s^2
Acceleration experienced by brother
Ab = 0.5* 0.523^2 = 0.1367 m/s^2
======
B)
Force required for sister
Fs = 0.41 * mass of sister
Force required for brother
Fb = 0.1367* mass of brother
Both forces must directed towards center
======
Comment in case any doubt, will reply for sure.. Goodluck

5) (10 pts) John is baby-sitting Casey, his 3-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As John starts across the street, he exerts a 58 N forward force on the wagon. There is a 20 N resistance force (friction) and the wagon and Casey have a combined weight of 302 N.
