A monoenergetic beam consists of unstable particles with total energies 40. A rigid cylinder rolls at constant speed without slipping on top of a horizontal plane surface. The acceleration of a point on the ... 45. A ball is dropped from a height h. As it bounces off the floor, its speed is 80 percent of what it was just before it hit the floor. The magnitude of the Earth's gravitational force on a point mass is F(r), where r is the distance from the Earth's center to the point ... 78. A particle of mass M moves in a circular orbit of radius r around a fixed point under the influence of an attractive force... A cylinder with moment of inertia 4 kg m^2 about a fixed axis initially rotates at 80 radians per second about this axis. A constant ...

A long, straight, and massless rod pivots about an end in a vertical plane. In configuration I, shown above, two small identical ... 74. Two circular hoops, X and Y, are hanging on nails in a wall. The mass of X is four times that of Y, and the diameter of X is also ... 82. A thin plate of mass M, length L, and width 2d is mounted vertically on a frictionless axle along the z-axis, as shown above.
