You observe a 2.0 kg particle moving at a constant speed of 3.8 m/s in a clockwise direction around a circle of radius 3.0 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

Find the volume of the ellipsoid x^2+y^2+5z^2=36.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

One number is said to be an "order of magnitude" larger than another number if choose one: a. it is 10 times larger. b. it is 5 times larger. c. it is 3 times larger. d. it is 100 times larger. e. it is 2 times larger.
