A 2.30-kg hoop 1.50 m in diameter is rolling to the right without slipping on a horizontal floor at a steady 2.90 rad/s.   Find the magnitude of the velocity vector for each of the points: (i) the highest point on the hoop; (ii) the lowest point on the hoop, (iii) a point on the right side of the hoop, midway between the top and the bottom, except as viewed by someone moving along with same velocity as the hoop.  Thank you!

A ferris wheel with a radius of 15 meters starts from rest and achieves it's maximum tangential speed of 2.4 meters per second in 33 seconds. What is the magnitude of the tangential acceleration

A diver runs horizontally off the end of a diving tower 3.5m above the surface of the water with an initial speed of 2.5 m/s. During her fall she rotates with an average angular speed of 2.6 rad/s How many revolutions has she made when she hits the water? Express your answer using two significant figures.Δθ= (?) rev

An object (with mass m = 6.20 kg) is attached to the free end of a massless string wrapped around a reel of radius R = 0.550 m and mass M = 4.00 kg. The reel is a solid disk, free to rotate in a vertical plane about the horizontal axis passing through its center, as shown in the figure. The suspended object is released from rest 3.50 m above the floor. Calculate the magnitude of the acceleration (in m/s2) of the object. Round your answer to 2 decimal places.Note: I=1/2 MR^2

Starting from rest, an airplane propeller begins to rotate with an angular acceleration a = 0.0600 rad/s2. The propeller radius is 60.0 cm. After exactly 4.00 seconds, calculate the total linear acceleration of the tip of the propeller. (The total linear acceleration is the vector combination of the tangential acceleration and the centripetal acceleration.) r= 60.0 cm

A 45.0-cm diameter disk rotates with a constant angular acceleration of 2.50 rad/s2. It starts from rest at t = 0, and a line drawn from the center of the disk to a point P on the rim of the disk makes an angle of 57.3° with the positive x-axis at this time. At t = 30 s, find d. the position of P (in degrees, with respect to the positive x-axis).
