A particle A, with a mass of 205 g, collides with one thin
homogeneous metal bar B, with a mass of 1.50 kg. The rod, which can
rotate freely about a horizontal shaft through point O at the upper
end of the rod, is before the shock at rest. Stuck in the shock

1. A thin, uniform bar of length L and mass M is supported by a frictionless horizontal surface. A ball of mass m travels to the right with speed v and strikes the bar. (top view) a. Assume the ball strikes the bar a distance d from the center of the bar and sticks to the bar. Find the velocity of the center of mass of the bar-ball system and them angular speed of the system. b.

A steel ball of mass m = 1 kg and a cord of negligible mass and
length L = 2 m make up a simple pendulum that can pivot without
friction about the point O (see below). This pendulum is released
from rest in a horizontal position and when the ball is at its
lowest point it strikes a block of mass m = 1 kg sitting at rest on
a shelf. Assume that the collision is perfectly elastic and...

1. A uniform horizontal bar of length L = 2.0 m and weight 144 N is pinned to a vertical wall and supported by a thin wire that makes an angle of 0 = 150 with the horizontal. A mass M, with a weight of 302 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 573 N. What is the maximum possible distance from the wall at which mass M can be placed...

Uniform bar OA rotates around endpoint O and position angle 0= 0 when the bar is horizontal and in static equilibrium. The mass of the bar is m = 20 kg, the length of the bar is L=1.2 m , k= 6000 N/m for the spring, and c= 320 N-s/m for the damper. The bar is initially at rest with 0 0 when force F(t) is applied to the end of the bar. Find the response 0(t) if force F(t)...
