A spring with a k value of 200 N/m is compressed by 20 cm. It has a 10 kg mass attached to it. A. What is the Potential energy of this spring? B. What is the Kinetic energy of the mass C. What is the velocity of the box when the spring is released

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.
