An aircraft performs a maneuver called an "aileron roll." During
this maneuver, the plane turns like a screw as it maintains a
straight flight path, which sets the wings in circular motion. If
it takes it 37 s to complete the circle and the wingspan of the
plane is 14.8 m, what is the acceleration of the wing tip?

The aircraft carrier initially sits at the dock at point D, facing north. It travels 1000 metres north then turns 90° to face the east, as shown in Figure 3. 90° 1000m (c) after turning 90 east. Assume a world coordinate frame with D as the origin. The x-axis points west, the y-axis points vertically up and the z-axis points north. One unit- one metre. representing...

A merry-go-round is rotating about its axis by 20.0rpm when a student with mass of 75.0 kg is at 1.0 m from the center. He starts moving toward the edge. Find angular velocity of total system when student is on the edge of merry-go-round. Merry-go-round has mass of 100 kg and radius of 3.0m and moment of inertia of disk is l= 1/2 MR2. Moment of inertia of boy is mR2. (use conservation of angular momentum)

A large turntable rotates about a fixed vertical axis, and has a moment of inertia of 900 kgm^2. A child of g is initially standing at the center of the turntable, and the system rotates at a rate of 2.5 rad/sec. The child suddenly runs along the radius and stops at a point 2.0 meters from the center. What is the angular speed of the turntable when the child is at this location? What frictional force would be needed to...
