A pendulum bob with length (L = 3m), vertically positioned is
perpendicularly to a Wooden block of mass on a plane surface. The
pendulum bob was raised to an angle (θ) to the horizontal and
release to strike the wooden block for at least twice. See the
table for details. As the bob hit the wooden block, it moved a
distance of Xwb at a speed (m/s) as shown in the diagram.

The disk rolls without slipping on the horizontal surface, and at the instant represented, the center O has the velocity vo = 2.2 m/s and acceleration 20 = 5.9 m/s2 with directions shown in the figure. For this instant, the particle A has the indicated speed u = 2.4 m/s and time rate of change of speed u = 5.9 m/s2, both relative to the disk with directions shown in the figure. Determine the absolute velocity VA and acceleration a...

A lead ball is thrown vertically downward with an initial speed of 3.9 m/s from the top of a building, which is 105 m high. (Compare this situation to: A ball is dropped from rest from the top of a building, which is 105 m high. ) The magnitude of the gravitational acceleration g = 9.8 m/s2 Keep 2 decimal places in all answers. In this problem, the following setup is convenient: Take the initial location of ball (the top...

Question 16 A An object of known mass M with speed vo travels toward a wall. The object collides with it and bounces away from the wall in the opposite direction in which the object was initially traveling. The wall exerts an average force Fo on the object during the collision. A student must use the equation Ap= FAt to determine the change in momentum of the object from immediately before the collision to immediately after the collision. Which side...
