Please help me!! I'm stuck! And please show all the work too!
8. The air horn on a fire engine has a frequency of 180 Hz as heard by the driver. What frequency is heard by a pedestrian who sees the vehicle traveling away from him at 22.0 m/s? (Assume it is a hot day and the speed of sound is 350 m/s)
11. A ball of mas M traveling at 10.0 m/s makes a head-on collision with a second ball of mass 2M that is initially at rest. After the collision, the first ball recoils at a velocity of -1.4 m/s. What is the velocity of the second ball after the collision?
17. A constant-pressure gas thermometer has a volume of 2.4 L at 20°C. The temperature increases until the volume is 3.2 L. What is the new temperature?

Please help with question, stuck on it. Please show all work of solution to comprehend it. 1.) In the simple kinetic theory of a gas, the molecules are assumed to be point-like objects (without any volume) so that they rarely collide with one another. In reality, each molecule has a small volume and so there are collisions. Let's assume that a molecule is a hard sphere of radius r. Then the molecules will occasionally collide with each other. The average...

She throws two stones vertically downward 1.00 s apart and observes that they cause a single splash. The first stone had an initial velocity of −1.00 m/s. (a) How long after release of the first stone did the two stones hit the water? (Round your answer to at least two decimal...

The catapult shown below is used to lay siege to your neighbor's cubicle. You fire 1-g peanut M&Ms at their desk until they surrender. The catapult arm moves from horizontal to 30° in 0.1 s, when it hits the crossbar and releases the projectile. Assume air resistance is negligible and the arm velocity is constant until it hits the crossbar. If the M&M...
