The figure shows a small wad of putty colliding into a bar. The bar is initially hanging at rest from a pivot located at one end of the bar. The collision is completely inelastic. The bar has mass M = 3.78 kilograms and length L = 1.12 meters. The putty wad has mass m = 131 grams and is moving horizontally with vi = 1.67 m/s just before colliding with and sticking to the bar. The putty wad collides with the bar at d = 0.83 meters from the pivot. Note that the size of the putty wad is negligible compared to the length of the bar. Calculate the angular velocity (rad/s) of the bar just after the collision.

A 13.8 kg block is sliding along a frictionless surface with a speed of 95.7 m/s. It collides with a second block of mass 93.1 kg. The second block is initially at rest. After the collision, the first block has rebounded with a speed of 26.1 m/s. If this collision is one dimensional, what is the speed in (m/s) of the second block after the collision?
A steel ball of mass 0.710 kg is fastened to a cord that is 89.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal, as shown in the figure.

A ballistic pendulum has a mass of 1.00 kg, it hangs from a string at rest when a bullet, mass 100.0 g is fired into it. The bullets speed is 50 m/s when it hits a pendulum. The two rise together immediately following the perfectly inelastic collision. Use the conservation of momentum and energy to determine how high they rise after the Impact.
A 0.00600 kg bullet traveling horizontally with speed 1.00 103 m/s strikes a 16.0 kg door, embedding itself 11.9 cm from the side opposite the hinges as shown in the figure below. The 1.00 m wide door is free to swing on its frictionless hinges. Imagine that the door is hanging vertically downward, hinged at the top, so that the figure is a side view of the door and bullet during the collision. What is the maximum height (in cm) that the bottom of the door will reach after the collision?
Two hockey players race for the puck in the middle of the rink. Player 1 has a mass of 69 kg and a velocity of 5.6 m/s at an angle of 32° with the rink board. Player 2 has a mass of 78 kg and a velocity of 7.1 m/s at an angle of 16° with the same board. The players become locked together in a completely inelastic collision. Find the energy in Joules lost in the collision.
One billiard ball (mass 118 grams) is moving due east at 5.0 m/s. A tennis ball (mass 321 grams) is moving due west at 4.0 m/s. The two balls have a glancing blow, which means they do not bounce along the same line as their original motion, but rather, deflect at an angle to their original paths. You measure the billard ball's motion as it moves 26.0° north of east, and you measure that the tennis ball is travelling 19.0° south of west. What is the speed of the billiard ball after the collision? Your Answer: Answer
The figure shows the view looking down onto an air hockey table. A puck collides with a stationary bar. The collision is completely inelastic.The bar has mass M = 1.44 kilograms and length L = 1.14 meters. The puck has mass m = 0.488 kilograms and is initially moving at vi = 6.83 perpendicular to the bar. The puck collides with the bar at a location of b = 0.505 meters from the center of the bar. Note that the size of the puck is negligible compared to the length of the bar. vf = 1.729. Calculate the angular speed (rad/s) about the center of mass of the puck-and-bar system just after the collision.
The Beast, friend of Belle, is determined to get in shape so that he doesn’t lose Belle. He loads up a barbell with two 20 kg plates on the right side and two 20 kg plates on the left side. The barbell is 2.2 m long and its unloaded mass is 20 kg. The two 20 kg plates on the right side are locked in place at 35 cm and 40 cm from the right end of the bar. Beast is unbalanced and his form is terrible so the two 20 kg plates on the left side have slipped. One is 30 cm from the left end of the bar and the other is 20 cm from the left end of the bar. Where is the center of gravity of this barbell with the four plates?
