Question

A 5 g marble is fired vertically upward using a spring gun. The spring must be compressed 6 cm if the marble is to just reach a target 36 m above the marble's position on the compressed spring.

A) What is the change in the gravitational potential energy of the marble-Earth system during the 36 m ascent?

B) What is the change in the elastic potential energy of the spring during its launch of the marble?

C) What is the spring constant of the spring?

Answer #1

In a spring gun system, a spring with a spring force constant
430 N/mN/m , is compressed 0.11 mm . When fired, 80.7 %%
of the elastic potential energy stored in the spring is eventually
converted into kinetic energy of a 6.50×10−2 kgkg
uniform ball that is rolling without slipping at the base of a
ramp. The ball continues to roll without slipping up the ramp with
89.6 %% of the kinetic energy at the bottom converted into an
increase in...

In a spring gun system, a spring with a spring force constant
370 N/m , is compressed 0.13 m . When fired, 79.1% of
the elastic potential energy stored in the spring is eventually
converted into kinetic energy of a 5.50×10−2 kg uniform
ball that is rolling without slipping at the base of a ramp. The
ball continues to roll without slipping up the ramp with 90.3 % of
the kinetic energy at the bottom converted into an increase in
gravitational...

The launching mechanism of a toy gun consists of a spring of
unknown spring constant, as shown in the figure below. If the
spring is compressed a distance of 0.200 m and the gun fired
vertically as shown, the gun can launch a 16.0-g projectile from
rest to a maximum height of 26.0 m above the starting point of the
projectile. Figures a and b show a ball in a toy spring gun,
oriented with its barrel vertical and opening...

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...

In a spring gun system, a spring with a spring force constant
350 N/mN/m , is compressed 0.11 mm . When fired, 81.0 %%
of the elastic potential energy stored in the spring is eventually
converted into kinetic energy of a 6.40×10−2 kgkg
uniform ball that is rolling without slipping at the base of a
ramp. The ball continues to roll without slipping up the ramp with
90.0 %% of the kinetic energy at the bottom converted into an
increase in...

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...

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...

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...

A toy gun uses a spring with a force constant of 300N/m to
propel a 15.0 g steel ball. If the spring is compressed 6.00 cm and
friction is negligible:
a) how much force is needed to compress the spring?
b) what is the maxium height that the ball can reach?
c) If the gun is fired at an angle of 7.50 degrees above the
horizontal, what is the maxium distance the ball will travel on
level ground?

A dart gun has a spring with a constant of 875 N/m. The spring
is initially compressed 5.5 cm. You fire a 0.075-kg dart from a
height of 0 m. The dart hits a wall at a height of 1.5 m. Ignore
air resistance.
What is the initial potential energy of the
spring?
What is the speed of the dart just before it hits the
wall?
The dart then penetrates 0.5 cm into the wall before coming to
rest.
