A.)A merry-go-round has a mass of 317 kg and a radius of 3.36 m. The merry-
go round is spinning such that it completes one revolution every 3.58 s
with a 63.6 kg man standing at its center. (a) What is the moment of
inertia of the merry-go-round if we assume it is a uniform circular disc?
tries: 0
B.)What is the angular velocity of the merry-go-round?
C.)If the person walks straight to the outside of the merry-go-round (i. e.
along a radial line), what is its new angular velocity of the merry-go-
round when he reaches its edge?

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.
