Just need some help getting started. What is it i need to use to get (a)
A suspicious package is sliding on a frictionless surface when it explodes into three pieces of equal masses and with the velocities:
(1) 7.0 m/s, north;
(2) 4.0 m/s 30 degrees south of west;
(3) 4.0 m/s 30 degrees...
A uniform solid cylinder of mass M = 4.0kg and radius R = 0.40m rotates about a vertical axis on frictionless bearings. A massless cord is wrapped around the cylinder and passes over a pulley of rotational inertia I = 0.020 kg*m2 and radius r = 0.10m. The free end of the cord is attached to a...
Four particles, each of mass 0.200kg, are placed at the vertices of a square with sides of length 0.500m. The particles are connected by rods of negligible masses. This rigid body can rotate in a vertical plane about a horizontal axis that passes through one of the particles (A for example, as...
In the attached figure, block A of mass 2.0kg slides on a horizontal frictionless table with velocity of 3.0m/s and collides with block B of mass 3.0kg initially at rest on the edge of the table. Block B moves with a horizontal velocity of 2.4m/s, just after the collision.
(a) Use...
Two pendulums, both of length l = 1.0m, are initially situated as shown in the below figure. The left bob has a mas m1 = 1.0kg and is held a distance d = 0.50m above the center of the right bob, of mass m2 = 2.0kg. The left pendulum is released and strikes the other. Assume that the collsion is...
A solid sphere of radius 0.100m and mass 14.3kg rolls without slipping up a surface inclined at 30 degrees to the horizontal. At a certain initial position the sphere's total kinetic energy is 90.1J.
(a) How much of this initial kinetic energy is rational?
(b) What is the speed of the center...
