Tutorial Exercise A 2.0-g particle moving at 5.5 m/s makes a perfectly elastic head-on collision with a resting 1.0-g object. (a) Find the speed of each particle after the collision. (b) Find the speed of each particle after the collision if the stationary particle has a mass of 10 g. (c) Find the final kinetic energy of the incident 2.0-g particle in the situations described in parts (a) and (b). In which case does the incident particle lose more kinetic energy? Step 1 The initial velocity of the target object is zero (v2i = 0). Let m, be the mass of the first particle, v,, its initial velocity, and v2r its final velocity. Let m, be the mass of the target object and vr its final velocity. From conservation of momentum before and after the collision, we have the following equation. m V1f + m2v2f = m,V1 + 0 For a perfectly elastic head-on collision, we have the following relationship between the objects' final velocities and initial velocities derived from conservation of momentum and…

A 1.30-kg wooden block rests on a table over a large hole as in the figure below. A 3.40-g bullet with an initial velocity v, is fired upward into the bottom of the block and remains in the block after the collision. The block and bullet rise to a maximum height of 16.0 cm. M m (a) Describe how you would find the initial velocity of the bullet using ideas you have learned in this chapter. O You can find the center of mass of the system based on how far the bullet stops inside the wooden block. Using the the work-energy theorem you can relate this the change in potential energy of the center of mass to the maximum height, U, = Mgy CM: Then, you can use the conservation of energy to relate this potential energy to the initial kinetic energy of the bullet. O Using the conservation of chemical energy you can relate the increased temperature of the block after the collision to the initial speed of the bullet. Then, you can use the conservation of mechanical energy for the bullet-block-Earth…
