You stand on a roof and fire a spring-loaded BB gun horizontally. The BB is fired from a height of 4 m above the ground. The BB has a mass of 3 grams and lands on the ground a distance of 30 m from where it was fired. The spring in the gun is compressed 12 cm before firing.

a) What is spring constant k of the spring?

b) How many newtons of force is required to compress the spring 12 cm?

A spring gun (k = 750 N/m) is loaded with a 55.3 g ball and compressed 12.0 cm. The gun is then fired horizontally off a 8.0 m high platform. (a) How fast will the ball be moving just as it leaves the spring gun (before it begins to fall)? (b) Determine the speed of the ball as it hits the ground. (Assume the ball is 8.0 m above the ground when it is fired.)

A small spring-loaded launcher is designed to fire steel ball bearings with masses of 0.3 kg . When setting the launcher, you compress the spring a distance of 13 cm . You then fire the launcher straight up and find that the projectiles reach a maximum height of 0.9 m above the point that they leave the launcher. You load another ball bearing, compress the spring a distance of 17 cm , and place it horizontally at the edge of...

In a ballistic pendulum, a spring gun, with a spring constant k, is aimed horizontally releasing a spring that has been compressed a distance x. A ball of mass m is fired at the bob of a pendulum. The bob (cup) has a mass M, and is suspended by a rod of negligible mass. After the collision, the ball stays inside the cup of the bob and swings through an arc, eventually gaining a height h. (a) Find the height...
