A bolt gun includes a spring of spring constant k = 11 N/m which is used to fire a bolt of mass m. The bolt leaves the gun at a speed of v = 4.1 m/s after the spring is compressed 1 cm. 1. What is the weight, Fg in Newtons, of the bolt? 2. What is the bolt’s speed when it hits the floor vf, in m/s, if it is fired horizontally at a height of h = 2 meters? I keep doing this problem and getting it wrong please help and explain well.
