A rock is moving around a circle as in the picture below. The rock is shown at an arbitrary time. Locations a, b, c, and d around the circle are reference locations. The coordinate system shown is positive up for the movement of the shadow. The radius of the circle is 8.7 m. The time for the rock to make one revolution is 5.7 sec. Find the value of the angular velocity (in rad/s). Give only the number in the box. Round to 2 digits past the decimal.

A 1.6 kg particle moves in a circle of radius 3.1 m. As you look down on the plane of its orbit, the particle is initially moving clockwise. If we call the clockwise direction positive, the particle's angular momentum relative to the center of the circle varies with time according to L(t) = 10 N · m·s - (5.0 N · m)t. (a) Find the magnitude and direction of the torque acting on the particle in N · m. Is...

A common amusement park ride is a Ferris wheel (see figure below, which is not drawn to scale). Riders sit in chairs that are on pivots so they remain level as the wheel turns at a constant rate.
A common amusement park ride is a Ferris wheel (see figure below, which is not drawn to scale). Riders sit in chairs that are on pivots so they remain level as the wheel turns at a constant rate. A particular Ferris wheel has a radius of 27 meters, and it makes one complete revolution around its axle (at location A) in 24 s. In all of the following questions, consider location A (at the center of the axle) as the...
