Question

A little boy jumps onto a small merry-go-round

(radius of 2.00 m) in a park and rotates for 2.30 s through

an arc length distance of 2.55 m before coming to rest. If

he landed (and stayed) at a distance of 1.75 m from the

central axis of rotation of the merry-go-round, what was

his average angular speed and average tangential speed?

Answer #1

Hope it helps...

Please give me a thumbs up...

And comment for further assistance..

A disk-shaped merry-go-round of radius 2.93 m and mass 185 kg
rotates freely with an angular speed of 0.621 rev/s . A 60.4 kg
person running tangential to the rim of the merry-go-round at 3.51
m/s jumps onto its rim and holds on. Before jumping on the
merry-go-round, the person was moving in the same direction as the
merry-go-round's rim.
What is the final angular speed of the merry-go-round?

A disk-shaped merry-go-round of radius 2.13 m and mass 185 kg
rotates freely with an angular speed of 0.631 rev/s . A 58.4 kg
person running tangential to the rim of the merry-go-round at 3.11
m/s jumps onto its rim and holds on. Before jumping on the
merry-go-round, the person was moving in the same direction as the
merry-go-round's rim.
Part A What is the final angular speed of the
merry-go-round?

A playground merry-go-round has a moment of inertia of 600 kg
m2. When the merry-go-round is at rest, a 20 kg boy runs
at 5.9 m/s along a line tangential to the rim and jumps on, landing
on the rim a distance of 3.0 m from the rotation axis of the
merry-go-round. The angular velocity of the merry-go-round is
then:
A.1.2 rad/s
B.0.38 rad/s
C.0.45 rad/s
D.0.56 rad/s
E.0.72 rad/s

A disk-shaped merry-go-round of radius 2.63 m and mass 155 kg
rotates freely with an angular speed of 0.558 rev/s. A 59.4 kg
person running tangential to the rim of the merry-go-round at 3.58
m/s jumps onto its rim and holds on. Before jumping on the
merry-go-round, the person was moving in the same direction as the
merry-go-round's rim. (a) Does the kinetic energy of the system
increase, decrease, or stay the same when the person jumps on the
merry-go-round?...

IP A disk-shaped merry-go-round of radius 2.84 m and mass 155 kg
rotates freely with an angular speed of 0.62 rev/s . A 61.1 kg
person running tangential to the rim of the merry-go-round at 3.17
m/s jumps onto its rim and holds on. Before jumping on the
merry-go-round, the person was moving in the same direction as the
merry-go-round's rim.

A 20-kg child running at 2.0 m/s jumps onto a playground
merry-go-round that has inertia 180 kg and radius 1.6 m. She is
moving tangent to the platform when she jumps, and she lands right
on the edge. Ignore any friction in the axle about which the
platform rotates. What is the rotational speed of the
merry-go-round and the child if the merry-go-round started from
rest? Express your answer with the appropriate units.

A merry-go-round with a a radius of R = 1.75 m and moment of
inertia I = 182 kg-m2 is spinning with an initial
angular speed of ω = 1.4 rad/s in the counter clockwise direection
when viewed from above. A person with mass m = 71 kg and velocity v
= 4.4 m/s runs on a path tangent to the merry-go-round. Once at the
merry-go-round the person jumps on and holds on to the rim of the
merry-go-round.

A merry-go-round (radius = 4 m) with a perfect frictionless
bearing is pushed with a force of 24 N by a young girl. She pushes
with a constant force that is oriented tangentially to the
edge of the merry-go-round. After she pushes the merry-go-round
through 14 full rotations (at which point she lets go) it is
spinning with an angular speed of 3 rad/s.
