A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...

-1. A flywheel rotating counterclockwise at 300 RPM takes 10.0 s to stop after it is switched off. a. Find the angular acceleration of the flywheel in rad/s2, assuming it is constant. (Show work, watch signs.) (12 points) b. How many revolutions does the flywheel make before stopping? (12 points) c. If the rotational inertia of the flywheel is 5.52 kg.m2 about its axle, find the frictional torque that stops the flywheel. (Show work, watch signs.) (12 points)

Q3: In the figure, a constant horizontal force of magnitude 16 N applies to a wheel of mass8 kg and radius 0.4 m from its center of mass. The wheel rolls smoothly on the horizontal surface. If the rotational inertia of the wheel is 0.85 kg.m2, find the a) linear and angular acceleration of the wheel, b) direction and magnitude of the frictional force on the wheel? Answer: a) a = 1.2 in/s2 and α = 3 rad/s. b) 6.4...

A 8.62 -m ladder with a mass of 21.1 kg lies flat on the ground. A painter grabs the top end of the ladder and pulls straight upward with a force of 234 N. At the instant the top of the ladder leaves the ground, the ladder experiences an angular acceleration of 1.87 rad/s2 about an axis passing through the bottom end of the ladder. The ladder's center of gravity lies halfway between the top and bottom ends. (a) What...

A 8.47 -m ladder with a mass of 24.0 kg lies flat on the ground. A painter grabs the top end of the ladder and pulls straight upward with a force of 231 N. At the instant the top of the ladder leaves the ground, the ladder experiences an angular acceleration of 1.68 rad/s2 about an axis passing through the bottom end of the ladder. The ladder's center of gravity lies halfway between the top and bottom ends. (a) What...

Consider the diatomic oxygen molecule, O_2, which is rotating in the xy plane about the z axis passing through its center, perpendicular to its length. At room temperature, the "average" separation between the two oxygen atoms is 1.21 times 10^-10 m (the atoms are treated as point masses, each with 2.66 times 10^-26 kg.) (a) Calculate the moment of inertia of the molecule about the z-axis. (b) If the angular velocity of the molecule about the z axis is 2.0...
