Acockroach rides the rim of a rotating merry-go-round. if the angular speed of this system (merry-go-round cockroach) is constant, does the cockroach have (a) radial acceleration and (b) tangential acceleration? if v is decreasing, does the cockroach have (c) radial acceleration and (d) tangential acceleration?

Amerry-go-round of radius r, shown in the figure, is rotating at constant angular speed. the friction in its bearings is so small that it can be ignored. a sandbag of mass m is dropped onto the merry-go-round, at a position designated by r. the sandbag does not slip or roll upon contact with the merry-go-round. how would you rank the following different combinations of m and r on the basis of the angular speed of the merry-go-round after the sandbag "sticks" to the merry-go-round from largest to smallest. a) m = 10kg, r = 0.25r b) m = 20kg, r = 0.25r c) m = 10kg, r = 0.50r d) m = 10kg, r = 1.0r e) m = 15kg, r = 0.75r f) m = 40kg, r = 0.25r

Two children (m = 31.0 kg each) stand opposite each other on the edge of a merry-go-round. the merry-go-round, which has a mass of 1.78 ✕ 10^2 kg and a radius of 1.2 m, is spinning at a constant rate of 0.48 rev/s. treat the two children and the merry-go-round as a system. (a) calculate the angular momentum of the system, treating each child as a particle. (give the magnitude.) (b) calculate the total kinetic energy of the system. (c) both children walk half the distance toward the center of the merry-go-round. calculate the final angular speed of the system.

A20kg boy stands on a small stationary (at rest) merry-go-round near the edge of the merry-go-round. the total moment of inertia of the system of merry-go-round with the boy on it about the center is 120kg m2 . the boy at the edge of the merry-go-round (radius of 2m) jumps off the merry-go-round in a tangential direction with a liner speed of 1.5m/s. what is the angular speed of the merry-go-round after the boy leaves it?
