Question

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.)

Answer #1

4) A spring loaded gun with a spring constant of 5100 N/m is
used to fire a 0.010 kg bullet off of a 110 m cliff. The spring is
compressed 0.10 m before launch. Assuming there is no air
resistance, what is the speed of the bullet just before it hits the
ground?

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...

90. The spring of a spring gun has a constant of
500N/m. It is compressed a distance x = 0.05m and a ball of mass
0.10kg is placed in the barrel against the compressed
spring.
Compute the maximum speed with which the ball leaves the gun when
released.( consider Conservation of Energy)

2. A nerf gun is loaded with a spring. The spring has a spring
constant of 400 N/m and the “ammunition” is a foam dart with a mass
of 0.2kg. When loaded, the spring is compressed 0.05m. (Ignore any
air resistance.)
a) How much elastic potential energy does the foam dart have
when the spring is compressed and the nerf gun is fully loaded?
b) How much kinetic energy does the foam dart have when the
spring is compressed and...

A spring-loaded toy gun is used to shoot a ball of mass
m=1.50kg straight up in the air. The spring has spring
constant k=667 N/m. If the spring is compressed a distance
of 19.0 cm 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 all movement occurs in a...

The potential energy stored in the compressed spring of a dart
gun, with a spring constant of 36.00 N/m, is 1.020 J.
Find by how much is the spring is compressed.
A 0.050 kg dart is fired straight up. Find the vertical distance
the dart travels from its position when the spring is compressed to
its highest position.
The same dart is now fired horizontally from a height of 2.30 m.
The dart remains in contact until the spring reaches...

The toy gun in the figure below consists of a spring with spring
constant k. It is loaded with a projectile of mass m and the spring
is compressed of a distance d. The toy gun is fired horizontally
and the bullet travels a total distance of L within the toy gun
before it is released.
A) Neglecting all resistive forces, determine the speed of the
projectile v0 once it exits the toy gun (i.e, express v0 in terms
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...

1.The potential energy stored in the compressed spring of a dart
gun, with a spring constant of 62.00 N/m, is 0.980 J. Find by how
much is the spring is compressed.
2.A 0.170 kg dart is fired straight up. Find the vertical
distance the dart travels from its position when the spring is
compressed to its highest position.
3.The same dart is now fired horizontally from a height of 4.30
m. The dart remains in contact until the spring reaches...

The toy gun in the figure below consists of a spring with spring
constant k. Itis loaded with a projectile of mass mand the spring
is compressed a distance d. The toy gun is fired horizontally and
the bullet travels a total distance Lwithin the toy gunbefore it is
released. A) Neglecting all resistive forces, determine the speed
of the projectile v0once it exits the toy gun(i.e., expressv0 in
terms of the known quantities k, m, L, d).B) Suppose now...
