QUESTION 1 A 4.3 kg mass moving in a circle (diameter = 2.4 m). The angular momentum varies in time as I = 5.9t2. What is the net torque acting on the mass at 7.1 s? Enter your answer to the tenth's place.
A 12.5kg mass moving in a circle(diameter=2.9m). The angular momentum varies in time as I=8t^2. What is the net torque acting on the mass at 14.3s? Enter answer to the tenths place.
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...

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
An object of mass 0.2 kg is moving in a circle of radius 2 m with translational acceleration a = 5 m/s^2 . What will be the total Torque on the object?
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.
