"The launching mechanism of a toy gun consists of a spring of unknown spring constant. If the spring is compressed a distance of 0.139 m and the gun fired vertically, the gun can launch a 25.1g projectile from rest to a maximum height of 24.5 m above the starting point of the projectile. Neglecting all resistive forces, determine the spring constant."© BrainMass Inc. brainmass.com March 4, 2021, 5:46 pm ad1c9bdddf
Potential energy stored in the spring gets converted to the kinetic energy of the projectile at first and when the ...
Solution shows how to calculate the spring constant from the given data with good explanation.
