physics and guns
A spring gun is made by compressing a spring in a tube and then latching the spring at the compressed position. A 4.97-g pellet is placed against the compressed and latched spring. The spring latches at a compression of [01] cm, and it takes a force of 9.12 N to compress the ...

Physics
A student gets a 2.9 kg mass to oscillate up and down on bottom of a light vertical spring by pulling her hand up and down on the top end of the spring. The spring is a real spring with a spring constant of 93 N/m and a damping constant of 0.7 N sec/m. (b) The student now ...
