Explanation:
)Sure, here are the equations in plain text format:
Rotational kinetic energy of the merry-go-round:
KE(merry-go-round) = 0.5 * I * ω^2
I = 0.5 * M * R^2
ω = (2π * rpm) / 60
Rotational kinetic energy of the children:
KE(child) = 0.5 * m * v^2
v = ω * R
Total rotational kinetic energy:
KE(total) = KE(merry-go-round)+ (2 * KE(child)
