In a spring gun system, a spring with a spring force constant 420 N/mN/m , is compressed 0.13 mm . When fired, 80.9 %% of the elastic potential energy stored in the spring is eventually converted into kinetic energy of a 6.10×10−2 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 gravitational potential energy at the instant it stops.
a)What is the velocity of the ball's center of mass at the base of the ramp?
Express your answer using two significant figures.
b)At this position, what is the velocity of a point at the top of the ball?
Express your answer using two significant figures.
c)At this position, what is the speed of a point at the bottom of the ball?
Express your answer using two significant figures.
d)What maximum vertical height up the ramp does the ball move?
Take the free fall acceleration to be 9.80m/s29.80m/s2. Express your answer using two significant figures.

The spring of a toy gun has a force constant of k = 533
N/m and negligible mass. The spring is compressed the length of the
gun barrel, 7.25 cm, and a 0.168-g ball is placed against the
compressed spring. A constant frictional force of 5.45-N acts on
the ball as it travels through the barrel. The ball leaves the
barrel at the moment that it loses contact with the spring. The toy
gun is ‘fired’ at a height of...

The potential energy stored in the compressed spring of a dart
gun, with a spring constant of 36.00 N/m, is 1.440 J. Find by how
much is the spring is compressed. A 0.070 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 4.30 m. The dart
remains in contact until the spring reaches...

The spring (force) constant of HF is 970 N/m (1 N = 1 kg m
s2 ).
(A) Calculate the fundamental frequency (expressed in units of
cm-1 ) and the zero point energy (in energy units, J).
(B) Earlier in the term we discussed the relationship between
the energy and the position and momentum uncertainties. For the
harmonic oscillator case, it would be
E ≥ ((Δp) 2 / 2µ) + (1 / 2) µω2 (Δx)

A spring with force constant k = 175 N/m is attached to the
ground. On top of the spring a 1.30 kg metal pan is attached. The
combination could be used as a scale, but we are going to do
something more interesting. We place a metal ball with mass 0.250
kg on the tray and then the tray is pushed down 0.150 m below its
equilibrium point and released from rest (take this as t = 0).

A spring that has a force constant of 1050 N/m is mounted
vertically on the ground. A block of mass 1.40 kg is dropped from
rest from height of 1.40 m above the free end of the spring. By
what distance does the spring compress?

A spring (70 N/m ) has an equilibrium length of 1.00 m. The
spring is compressed to a length of 0.50 m and a mass of 2.2 kg is
placed at its free end on a frictionless slope which makes an angle
of 41 ? with respect to the horizontal. The spring is then
released. (Figure 1)
Part A
If the mass is not attached to the spring, how far up the slope
from the compressed point will the mass move...

A horizontal spring with a spring constant of 190 N/cm is
compressed 6.3 cm. A wooden block with a mass of 1.5 kg is placed
in front of and in contact with the spring. When the spring is
released it pushes the block, which slides on a frictionless
horizontal surface for some distance. The block then slides up a
frictionless incline of 27 above the horizontal and comes to a
momentary stop before sliding back down. The system is the...
