Cloud and precipitation Droplet fall speed. The terminal velocity of an object falling through a fluid is usually determined by a force balance between gravity and some drag force trying to slow the object down. The drag force depends on the velocity of the particle and therefore can be solved for when the forces are equal and opposite.

Aug 05, 2013 · A 655 N diver leaps into the water from a height of 10.0 m. What is his speed 2.00 m above the water? An even simpler method was to have your zero displacement position be 2.00 meters above the surface of the water, then the energy equation would be: A sled and rider together have a mass of 87 kg. They are atop a hill elevated at 42.5(.

Speed of sound through air (gas) = 343 m/s or 767 mph. Speed of sound through water (liquid) = 1,482 m/s or 3,315 mph. Speed of sound through steel (solid) = 5,790 m/s or 12,950 mph. The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour.
