Gun Darts
How quickly leave the Dart Gun?
A dart gun loaded with spring (k = 150 N / m) is compressed 4.0 cm and shoot a dart program 3.2.
Assuming the spring is a linear spring without mass … The potential energy stored in the spring is converted into kinetic energy of the projectile. linear spring potential energy is U = 0.5 * k * x ^ 2, while the kinetic energy of a projectile is E = 0.5 * m * v ^ 2. Equal to EU framework, we simplified to obtain v ^ 2 * k = x ^ 2 / m. Plug your numbers, and away you go!
