I can never remember whether the '100 T' is the gross weight of the ship or the weight of the cargo it can carry. Let's say it's the gross loaded weight. / / / A 100 ton floating ship displaces 100 tons of water, and the bbuoyant force on it is 100 tons.

A merry-go-round is rotating at an angular speed of 0.2 radians/s. Its motor falls off and it rotates freely. A technician jumps

I am Lyosha [343]

Answer:

I₁ =1250 kg.m²

Explanation:

Given that

Angular speed of Merry ,ω₁= 0.2 rad/s

Angular speed of technician ,ω₂= 0.04 rad/s

Moment of the inertia of the technician ,I₂= 5000 kg.m²

Lets assume that

Moment of the inertia of merry with respected to the ground=I₁

There is no any external torque ,that is why angular momentum of the system will be conserve.

Now by conserving angular momentum

I₁ ω₁=(I₁+I₂)ω₂

I₁ x 0.2 = (I₁ +5000 ) x 0.04

I₁ (0.2-0.04) = 5000 x 0.04

$I_1=\dfrac{5000\times 0.04}{0.2-0.04}$

I₁ =1250 kg.m²
