Angelica starts spinning the merry-go-round, giving it an angular velocity of 8 rad/s , then she stops pushing it. boris runs with a speed of 9 m/s directly toward the center of the merry-go-round. he jumps and lands on the edge of the merry-go-round. what is the angular speed of the merry-go-round once boris lands on it?

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?

Madison pushes with a 210-n horizontal force on a 24-kg crate of coffee resting on a warehouse floor. the force of friction on the crate is 74 n. what is the acceleration?
