What is the period of the merry go round?
What is the period of the merry go round?
Question: A 4.1-m-diameter merry-go-round is initially turning with a 3.4 s period.
What is the diameter of a merry go round?
Merry Go Round 10′ Diameter.
How many revolutions does the merry go round make?
The merry-go-round makes one complete revolution every two seconds (demo).
How big is a 5.0 m diameter Merry Go Round?
This problem has been solved! A 5.0-m-diameter merry-go-round is initially turning with a 4.0 s period. It slows down and stops in 20 s. Before slowing, what is the speed of a child on the rim (in m/s)?
How long does it take for a merry go round to turn?
A 5.0-m-diameter merry-go-round is initially turning with a 4.0 s period. It slows down and stops in 20 s. Before slowing, what is the speed of a child on the rim (in m/s)?
What is the final velocity of the Merry Go Round?
Final velocity (linear and angular) is zero because the problem says the merry-go-round stops. Try thinking of this in terms of linear kinematics, making the appropriate substitutions. What you did here was to convert from rad/s to revolutions per second; so that should be 2.48 rev/s.
Is Merry Go Round circular motion?
The motion of a merry go round is circular motion. In this motion the merry go round exerts a centripetal force on the person riding it. To keep moving in this motion the merry go round must exert more force on the person.
Why do you fall off a merry go round?
Generally speaking, the larger the circle you move in, the greater the centripetal force you experience. So, the farther you move away from the center of the merry-go-round, the more force the merry-go-round must exert on you to keep you moving in that circle.
How do you calculate total torque?
A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. and the magnitude of the torque is τ = N m.
What force does not cause any torque?
Any force that is along a line which passes through the axis of rotation produces no torque. Note that torque is a vector quantity, and, like angular displacement, angular velocity, and angular acceleration, is in a direction perpendicular to the plane of rotation.
What force throws you off a merry go round?
Coriolis force
As on the merry-go-round, any motion in Earth’s northern hemisphere experiences a Coriolis force to the right.
Where would you feel the least dizzy on a merry go round?
The next time you’re at a park, watch children playing on a merry-go-round and you’ll notice that kids sitting in the center of the merry-go-round don’t get as dizzy as those hanging on the edge.
What is the formula for calculating frictional torque?
τ fric = b 0 sgn ( ω ) + b 1 ω , where b0 is the Coulomb friction torque (sgn(ω) just returns the sign of ω) and b1 is a viscous friction coefficient.
