Two billiard balls move at right angles and meet at the origin. Ball A (the cue ball, 175 g) is initially moving upward along the y axis at vA = 2.0 m/s, and ball B (a numbered ball, 155 g) is moving to the right along the x axis at vB = 3.7 m/s. After the collision, ball B is moving along the positive y axis at 2.85 m/s.
What is the final velocity & direction of Ball A?
A monatomic ideal gas (? = 5/3) is contained within a perfectly insulated cylinder that is fitted with a movable piston. The initial pressure of the gas is 1.82 × 105 Pa. The piston is pushed so as to compress the gas, with the result that the Kelvin..

A wave travels along a string at a speed of 295m/s. What will be the speed if the string is replaced with one made of the same material and under the same tension however having twice the radius?
To water the yard you use a hose with a radius of 3.50 cm. Water flows from the hose with a speed of 1.10 m/s. If you in part block the end of the hose so the effective radius is now 0.55-cm, with what speed does water spray from the hose.
