What is the magnitude of the angular momentum of a 1.0-g particle moving counterclockwise (as viewed from above) with an angular speed of 5 pi rad/s in a horizontal circle of radius 16 cm ? Express your answer using two significant figures. L = kg middot m^2/s What is the direction of the angular momentum upward downward
10. Determine the magnitude of energy and the angular momentum of a particle with mass m moving through the circle path with radius ro because of the attraction of the magnitude inversely proportional to the radius F2
Please solve only (e), and only if you're certain you're correct. Thank you. Angular momentum and choice of origin: Adding angular momentum to a collision problem often feels confusing or ad hoc. What we're going to do here is verify that adding angular momentum to a collision problem isn't incompatible with anything we've done previously, by considering a very simple collision problem: One particle, moving with a velocity vo, collides with another, sticks with it, and then they move together...
This is an interesting phenomenon, and a very difficult one to explain. Both torque and angular momentum must be treated as vectors. Torque causes angular momentum to change according to the following equation: delta L rightarrow = rightarrow delta T To use this equation the direction of a torque vector must be defined. Follow the moment arm with the fingers of your right hand. Then turn your fingers to follow the force. As you do this, your thumb will point...
You observe a 2.0 kg particle moving at a constant speed of 3.6 m/s in a clockwise direction around a circle of radius 4.0 m. (a) What is its angular momentum about the center of the circle? kg·m2/s (b) What is its moment of inertia about an axis through the center of the circle and perpendicular to the plane of the motion? kg·m2 (c) What is the angular velocity of the particle? rad/s
Part A Calculate the magnitude of the angular momentum of the Venus in a circular orbit around the sun. The Venus has mass 4.87x1024 kg , radius 6.05x106m, and orbit radius 1.08x109 m. The planet completes one rotation on its axis in 243 days and one orbit in 224.7 days. IVO AED ?

At one instant in time, the situation shown in the figure happens. A 7.01 kg particle P has a position vector r of magnitude 3.19 m and angle θ1 = 45° and a velocity vector v of magnitude 1.37 m/s and angle θ2 = 30°. Force F of magnitude 9.13 N and angle θ3 = 30° acts on P. All three vectors lie in the xy-plane. About the origin, what is the angular momentum of P, in kg•m2/s? Determine the...

Calculate the angular momentum for a rotating disk, sphere, and rod. (a) A uniform disk of mass 16 kg, thickness 0.5 m, and radius 0.9 m is located at the origin, oriented with its axis along the y axis. It rotates clockwise around its axis when viewed from above (that is, you stand at a point on the +y axis and look toward the origin at the disk). The disk makes one complete rotation every 0.7 s. What is the...
In a long jump, an athlete leaves the ground with an initial angular momentum that tends to rotate her body forward, threatening to ruin her landing. To counter this tendency, she rotates her outstretched arms to "take up" the angular momentum (see the figure below). In 0.650 s, one arm sweeps through 0.500 rev and the other arm sweeps through 1.000 rev. Treat each arm as a thin rod of mass 3.9 kg and length 0.59 m, rotating around one...
