wheel that is rotating in the direction shown by the curved arrow. If she rotates the bicycle wheel 180° by switching the positions of her left and right hand, which direction will

A projectile of mass .050 kg moves to the right with a speed of 4.0 m/s. The projectile strikes and sticks to the end of a rod of mass 0.8 kg, at length 1.2 m from the rod's centre. The rod may rotate freely around a stationary axle pinned through the rod's centre of mass. Find the magnitude of the angular velocity, ω, of the system right after the collision. Select one: a. 0.00 rad/s b. 0.27 rad/s c. 0.53 rad/s d. None of the other answers are correct e. 1.05 rad/s

In the image below pivot is placed at the center of mass of the stick (mass = 0.097 kg). If the block (0.022 kg) is placed at 0.766 m it will rotate the block-stick system around the pivot. Calculate the following. (Istick = 1/12 ML^2)

A sphere of mass 1.0 kg and radius 0.21 m is suspended on the rod of length 0.49 m and mass 0.43 kg as it is shown in the figure. System can rotate around uppermost point. A bullet of mass 0.02 kg strikes the sphere as it shown in the figure (aiming directly to the center of the sphere) and embeds. Find minimum velocity of bullet which allows this system to just clear the top. The answer is 300.719752599215. Please show all steps on how to get to that answer.

A bicycle is traveling north at 6.84 m/s. The mass of the wheel, 2.6 kg, is uniformly distributed along the rim(I=mr2), which has a radius of 17.89 cm. What are the magnitude(in kg m2/s) and direction of the angular momentum of the wheel about its axle?

A clown sits on a unicycle and rides it BACKWARDS (moving in the opposite direction he is facing). The wheel spins around its fixed rotation axis in normal fashion. In which direction does the angular momentum vector of the unicycle wheel point? Group of answer choices a) To his/her right b) To his/her left c) foward (the direction he is facing) d) backward (the direction of motion) e) In the upward direction (toward the sky)

In Figure 2, two skaters, each of mass 52 kg, approach each other along parallel paths separated by 2.6 m. They have opposite velocities of 1.5 m/s each. One skater carries one end of a long pole of negligible mass, and the other skater grabs the other end as she passes. The skaters then rotate around the center of the pole. Assume that the friction between skates and ice is negligible and the skaters can be treated as mass points. Calculate (a) the angular speed of the skaters (b) the kinetic energy of the two-skater system Next, the skaters pull along the pole until they separated by 1.0 m. Calculate (c) the new angular speed of the skaters (d) the new kinetic energy of the two-skater system 1.5 m/s 2.6 m 1.5 m/s Figure 2

A bird flies overhead from where you stand at an altitude of 310.0ĵ m and at a velocity horizontal to the ground of 14.0î m/s. The bird has a mass of 1.8 kg. The radius vector to the bird makes an angle ? with respect to the ground. The radius vector to the bird lies in the xy-plane. What is the bird's angular momentum (in kg · m2/s) about the point where you are standing? (Express your answer in vector form.)

Consider the figure above consisting of three particles of mass m attached to a massless rod.  Given an axis of rotation through point P, the rod rotates as shown in the figure.  If the rod is released from rest in the horizontal position at t = 0.  What is the angular acceleration of the system (rod and three particles) immediately after being released?  Let d = 2.50 m.
