A4.0-m-diameter playground merry-go-round, with a moment of inertia of

500kg? m2 is freely rotating with an angular velocity of 2.0rad/s . ryan, whose mass is 70kg , runs on the ground around the outer edge of the merry-go-round in the opposite direction to its rotation. still moving, he jumps directly onto the rim of the merry-go-round, bringing it (and himself) to a halt. how fast was ryan running when he jumped on?

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
