Tutorial: Angular Momentum and Torque III. Angular Momentum The angular momentum of a point particle is defined by: L = ixp. Here, is a vector that points from the point of rotation (or point around which the angular momentum is calculated) to the location of the particle and p = mb is the linear momentum of the particle. A Your little brother Joey is playing with his toy airplane. The airplane is tied to a string and its motor makes...
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...

6. Angular Momentum and Torque on a Meteor A meteor enters Earth's atmosphere and is observed by someone on the ground before it burns up in the atmosphere. The vector 25 m i +25 m j gives the position of the meteor with respect to observer. At the instant the observer sees the meteor, it has linear momentum p 1.5 kg -2.0) m/s 3 and it is accelerating at a constant rate of 2.0 m/s(-3) along its path, which for...
