3.5-m-diameter merry-go-round is rotating freely with an angular velocity of 0.78 rad/s . its total moment of inertia is 1710 kgâ‹…m2 . four people standing on the ground, each of mass 66 kg , suddenly step onto the edge of the merry-go-round.
a. what is the angular velocity of the merry-go-round now?
b. what if the people were on it initially and then jumped off in a radial direction (relative to the merry-go-round)?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
