A brave child decides to grab onto an already spinning merry‑go‑round. The child is initially at rest and has a mass of 34.5 kg.

ozzi

Answer:

$I_1 = 32.5 kg m^2$

Explanation:

Here as we know that total angular momentum is always conserved for child + round system

so here by angular momentum conservation we have

$I_1 \omega_1 = (I_1 + I_2)\omega_2$

here we have

$I_2 = mR^2$ (inertia of boy)

$I_2 = (34.5)(1.45^2)$

$I_2 = 72.5 kg m^2$

now we have

$I_1(2\pi 55) = (I_1 + 72.5)(2 \pi 17)$

$I_1 = (I_1 + 72.5)(0.31)$

$I_1(1 - 0.31) = 22.4$

$I_1 = 32.5 kg m^2$
