Suppose a 0.270 -kg mass on a spring-loaded gun that has been compressed 0.210 m has elastic potential energy of 24.0 J. How high above the spring's equilibrium point can the gun fire the mass if the gun is fired straight up?
Homework Answers
From the conservation of energy
Initial elastic potential energy = Final gravitational potential energy
there fore 24 J = mgh
height above the equilibrium point h = 24/mg = 24/(.270*9.8) = 9.07 meters

9. A spring-loaded toy gun is used to shoot a ball of mass m-2.50 kg straight up in the air, as shown below. The spring has spring constant k-500 NI/m. If the spring is compressed a distance of 20.0 centimeters from its equilibrium position y-0 and then released, the ball reaches a maximum height hmax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of the gun. Assume that...

A spring-loaded toy gun is used to shoot a ball of mass m=1.50 kg straight up in the air, as shown in (Figur 1) . The spring has spring constant k =667 N/m. If the spring is compressed distance of 25.0 centimeters from its equilbriurn position y = 0 and then released, the ball reaches a maximum height hax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of...

A hockey puck of mass
m = 0.170 kg is loaded into a spring gun with spring
constant k = 306 N/m. The spring is compressed by a
distance d = 0.100 m and then released, launching the puck
onto a horizontal and frictionless surface of ice with speed v in
the positive x-direction. This puck then collides with
another puck of the same mass which is at rest at the origin.
After the collision the two pucks move away...

A dart gun consists of a spring (k = 367 N/m) and a 25.0 g dart. When the dart is loaded into the gun, the spring is compressed 7.0 cm. The gun is aimed straight up and fired. a) How high does the dart go, ignoring air resistance of course? b) How fast is the dart going when it comes back down to the horizontal level at which it was fired?

1. 2. A spring-loaded toy gun is used to shoot a ball of mass M straight up in the air. The ball is not attached to the spring. The ball is pushed down onto the spring so that the spring is compressed a distance S below its unstretched point. After release, the ball reaches a maximum height 35, measured from the unstretched position of the spring (see diagram below). Maximum Height Spring unstretched Spring compressed Mass released from west will...
