A block of mass M on a horizontal frictionless table is connected to a spring (constant k). The block is at the left and attached to an horizontal spring , and the right end of the spring is itself attached to the wall. The block is set in motion so that it oscillates about its equilibrium point with a certain amplitude Ao. The
A block with mass attached to a horizontal spring with force constant is moving with simple harmonic motion having amplitude. At the instant when the block passes through its equilibrium position, a lump of putty with mass m is dropped vertically onto the block from a very small height and sticks to it.
For this value of m, w
Cross-linking a Polymer
The objective of this experiment is to crosslink a polymer and observes the changes in the physical properties of the polymer as a result of the crosslinking. Changes in physical properties are also sensitive to amount of crosslinking. This experiment could be expanded to investigate vario
In preparation for shooting a ball in a pinball machine, a spring (k= 675 N/m) is compressed by 0.0650 m relative to its unstrained length. The ball (m= 0.0585 kg) is at rest against the spring at point A. When the spring is released, the ball slides (without rolling) to point B, which is 0.300m higher than point A. How fast
A solid, horizontal cylinder of mass 10.4 kg and radius 1.13 m rotates with an angular speed of 6.81 rad/s about a fixed vertical axis through its center. A 0.251 kg piece of putty is dropped vertically onto the cylinder at a point 0.864 m from the center of rotation, and sticks to the cylinder. Determine the final angular speed
A rubber ball of mass 0.05kg is dropped from a height of 10 cm above a table top. it bounces off the table and rises to the same height.
a. What is the shape of the graph of the force exerted on the ball by the table as a function of time?
b. If the rubber ball was in contact with the table for 30ms, what is the avg force
Suppose the force acting on a tennis ball (mass 0.065 kg) points in the +x direction and is given by the graph of Fig. 7-30 as a function of time.
Figure 7-30 in attached document.
(a) Use a graphical method to estimate the total impulse given the ball.
(b) Use a graphical method to estimate the velocity of the ba
A 0.343 kg croquet ball makes an elastic head-on collision with a second ball initially at rest. The second ball moves off with one half the original speed of the first ball. 1) What is the mass of the second ball? And 2) what fraction of the original kinetic energy gets transferred to the second ball?
