Problem 42P

Billiard ball A of mass mA = 0.400 kg moving with speed vA = 1.80 m/s strikes ball B, initially at rest, of mass mB = 0.500 kg. As a result of the collision, ball A is deflected off at an angle of 30.0° with a speed v’A = 1.10 m/s. (a) Taking the x axis to be the original direction of motion of ball A, write down the equations expressing the conservation of momentum for the components in the x and y directions separately. (b) Solve these equations for the speed v'B and angle θ'B of ball B. Do not assume the collision is elastic.

Chapter 2: Basic Chemistry and Biochemistry-Part 1 by Mehrnaz Ighani . Chemistry: the basis of all physiological reactions such as movement, digestion, metabolism, and etc. . Chemistry has 2 subdivisions: 1. Basic chemistry 2. Biochemistry . Matter: any object that has mass and occupies space Weight is mass+ the force of gravity . 3 states of matter: 1. Solid: defined shape and volume 2. Liquid: changeable shape but defined volume 3. Gas: changeable shape and volume . Energy: the capacity to do work or put matter into motion Doesn’t have mass, nor does it take up space The greater the work done, the more energy needed . Energy exists in 2 forms: 1. Kinetic energy (energy in action) 2. Potential energy (stored energy) Energy can be tran
