an amusement park contains a big cylinder of radius R oriented horizontally and rotating with angular velocity w about its axis. Achild of mass m is sitting partway up one side so that she remains at rest a distance h above the bottom of the rotating cylinder. There is the coefficient of kinetic friction between child and the cylinder. In terms of R and h ,

how much is the angle?

What is the normal force N acting on the child ?

Assuming the maximum value of the coefficient of kinetic friction is 1, what is the maximum value of h?

In an amusement park ride passengers stand inside a hollow cylinder of 2.12 meter radius. The cylinder is then spun and the floor of the cylinder is dropped away as the passengers stick to the wall. If the coefficient of static friction between the passengers and the wall is 0.551, with what angular velocity (rpm) does the cylinder have to be rotating so the passengers don’t slide down the wall?

A cylinder of radius R = 50 cm has rotational inertia I. It is rotating with angular velocity w = 2 rad / s. A bullet of mass m = 160 grams and speed v = 1500 m / s hits the cylinder at a distance 40 cm from its axis and remains there. Both the cylinder and the bullet stop after collision. Find I in units of kg - m2.

A hollow cylinder (hoop) of mass M and radius R starts rolling without slipping (with negligible initial speed) from the top of an inclined plane with angle theta. The cylinder is initially at a height h from the bottom of the inclined plane. The coefficient of friction is u. The moment of inertia of the hoop for the rolling motion described is I= mR^2. a) What is the magnitude of the net force and net torque acting on the hoop?...

In an amusement park ride, a giant, wheel-shaped tube rotates about a vertical axis and when the angular velocity of the tube gets to a certain value, the floor of the cage drops out and the riders “stick” to the wall of the cage. a) Draw a FBD of all the forces acting on a rider once the floor drops out b) If the coefficient of static friction between the wall and the rider is 0.320 and the cage has...

A playground ride consists of a disk of mass M = 59 kg and radius R = 1.9 m mounted on a low-friction axle. A child of mass m = 18 kg runs at speed v = 2.2 m/s on a line tangential to the disk and jumps onto the outer edge of the disk. (b) Relative to the axle, what was the magnitude of the angular momentum of the child before the collision? L|C| =    (c) Relative to the...

A) A man holds a 185-N ball in his hand, with the forearm horizontal (see the figure). He can support the ball in this position because of the flexor muscle force , which is applied perpendicular to the forearm. The forearm weighs 18.2 N and has a center of gravity as indicated. Find (a) the magnitude of and the (b) magnitude and (c) direction (as a positive angle counterclockwise from horizontal) of the force applied by the upper arm bone...
