The figure below shows a stationary block of mass 1 kg resting on a frictionless surface and attached to one end of a spring with spring constant 900 N/m. The spring is initially at its relaxed length and is connected to a rigid wall. A bullet of mass 5 g moving with speed 400 m/s is fired into the block and emerges from the other end of the block. The collision is not elastic. If the block moves a distance of 5 cm to the right after impact, find the speed v of the bullet after the collision and before it hits the wall. Assume that the block doesn't start moving until the bullet completely emerges from the block. (Hint: conserve momentum during the collision, conserve energy after the collision.) 400 m/s www 5 cm www

A small wooden block with mass 0.800 kg is suspended from the lower end of a light cord that is 1.60 m long. The block is initially at rest. A bullet with mass 12.0 g is fired at the block with a horizontal velocity v0. The bullet strikes the block and becomes embedded in it. After the collision the combined object swings on the end of the cord. When the block has risen a vertical height of 0.800 m, the tension in the cord is 4.80 N. What was the initial speed v0 of the bullet?
In a particular crash test, a car of mass 1 500 kg collides with a wall as shown in Figure 9.5. The initial and final velocities of the car are ν→i = 215.0î m/s andν→f = 2.60î m/s, respectively. If the collision lasts 0.150 s, find the impulse on the car during the collision and the average net force exerted on the car.
A cue ball at rest on a frictionless pool table is hit dead center by a pool stick, giving it an impulse of +1.25 N · s. The ball slides (the combination of hitting the ball dead center and no friction allows this to happen) along the table and makes a head-on elastic collision with another pool ball. If both pool balls have a mass of 0.161 kg, determine the velocity (in m/s) of the second ball the instant after the collision.
A ball of mass 0.210 kg that is moving with a speed of 7.8 m/s collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.8 m/s.
Two shuffleboard disks of equal mass, one orange and the other yellow, are involved in an elastic, glancing collision. The yellow disk is initially at rest and is struck by the orange disk moving with a speed of 5.00 m/s. After the collision, the orange disk moves along a direction that makes an angle of 37.0° with its initial direction of motion. The velocities of the two disks are perpendicular after the collision. Determine the final speed of each disk.
A small block of mass 20.0 grams is moving to the right on a horizontal frictionless surface with a speed of 0.400 m/s. The block has a head-on elastic collision with a 40.0 gram block that is initially at rest. Since the collision is head-on, all velocities lie along the same line, both before and after the collision. a) What is the speed of the 20.0 gram block after the collision? (b) What is the speed of the 40.0 gram block after the collision?
A 10.0-g marble slides to the left with a velocity of magnitude 0.400 m/s on the frictionless, horizontal surface of an icy New York sidewalk and has a head-on, elastic collision with a larger 30.0-g marble sliding to the right with a velocity of magnitude 0.200 m/s. Find the velocity of each marble (magnitude and direction) after the collision. (Since the collision is head-on, all the motion is along a line.) (b) Calculate the change in momentum (that is, the momentum after the collision minus the momentum before the collision) for each marble.
Two people are riding inner tubes on an ice-covered (frictionless) lake. The first person has a mass of 65 kg and is travelling with a speed of 5.5 m/s. He collides head-on with the second person with a mass of 140 kg who is initially at rest. They bounce apart after the perfectly elastic collision. The final velocity of the first person is 2.1 m/s in the opposite direction to his initial direction. (a) Are momentum and kinetic energy conserved for this system? Explain your answer. (b) Determine the final velocity of the second person.
We have a disk that is 1.49 kg and is traveling at 3.18 m/s to the right. It hits the end of a stick with a mass of 1.61 kg and an overall length of 3.2 m. The stick was originally oriented so that its long axis was perpendicular to the path of the disk, but it rotates after the collision. However, the disk continues moving along the same path after the collision. Assume that the collision is perfectly elastic, there is no friction, and the disk has an insignificant width. 1. Find the speed of the disk after collision. 2. Find the angular speed of the stick after collision.
