Problem 42

A 4.00-g bullet is moving horizontally with a velocity of 1355 m/s, where the 1sign indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the fi rst block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are moving after the collision with the bullet. The mass of the fi rst block is 1150 g, and its velocity is 10.550 m/s after the bullet passes through it. The mass of the second block is 1530 g. (a) What is the velocity of the second block after the bullet embeds itself? (b) Find the ratio of the total kinetic energy after the collisions to that before the collisions.

Chapter 1: What is Sound The Very First Steps 1. We use the word “sound: to describe at least two different things: a. Sensation of the auditory nerve of our ear. i. Means what we actually perceive. b. The wave. i. Traveling through the medium which somehow causes the sensation of hearing. 2. Acoustics is a science of sound. a. Acoustics is an interdisciplinary science which includes Physics, Engineering, Theory of Music, Psychology, Physiology, Architecture, and the study of sound we cannot hear: Ult
