Answer:
The correct answer is
1. the boy 2.
Explanation:
Since Tangential acceleration = v²/r then the
v = ωr and v² = ω²r² then the tangential acceleration = ω²r²/r = ω²r
This shows that since ω is the same for both of them, the boy with greater r has the most acceleration.
The tangential acceleration 
α·r
