Question

With a BALL of mass 10 kg you compress a SPRING of k = 1.00 x 106 kg s-2 by x = 10 cm. How HIGH does the BALL fly upward when you release it

Answer #1

3a. With a BALL of mass 10 kg you compress a SPRING of k = 1.00
x 106 kg s-2 by Dx = 10 cm. How HIGH does the BALL fly upward when
you release it? B. A person of mass 60 kg jumps from a height of 3
m. She lands on her feet but her knee joints each compress by 0.5
cm. What force did she put on her knees?

A spring with k=45 N/m is oriented vertically with one end fixed
to the ground. A 0.5 kg mass on top of the spring compresses
it.
1. Provide a conceptual explanation of what is happing for each
of the following cases :
a. You hold the mass while you gently compress the spring, and
when you release the mass it sits at rest atop the spring.
b. You place the mass on the uncompressed spring and release
it.
c. You...

a
0.2 kg mass is pushed down against a vertical spring with a spring
constant k = 1000 N/m. when the spring is compressed by 10 cm, the
object is let go. what vertical height above the release point will
the obhect reach? give answer in meters

You hang a 10 kg mass off of a vertical spring with a spring
constant k = 15 N/m. How much does the spring stretch? Then, you
take the spring and lay it flat on a friction-less table, anchoring
one end. You attach the same mass to free end, pull it back 0.25
meters from its equilibrium position, and let go. How fast is the
mass going at the equilibrium position?

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...

A 0.280 kg block on a vertical spring with a spring constant of
4.12 × 10^3 N/m is pushed downward, compressing the spring 0.0600
m. When released, the block leaves the spring and travels upward
vertically. The acceleration of gravity is 9.81 m/s2 . How high
does it rise above the point of release? Answer in units of m.

A 10-cm-long spring is attached to the ceiling. When a 2.0 kg
mass is hung from it, the spring stretches to a length of 15
cm.What is the spring constant k? How long is the spring when a 3.9
kg mass is suspended from it?

A toy car, with mass m = 200 g is given a velocity of 10 m s at
the top of the first hill with height h = 1 m. The toy car goes
down the hill to the ground and starts up the second hill of height
h = 2 m. At the top of the hill is a spring, with spring constant k
= 100 N C . How far does the spring compress when the car gets...

A block with mass 0.382 kg is attached to a horizontal spring
with spring constant k = 1.28 N/m on a frictionless surface. The
block is pulled 0.753 m from equilibrium and released. (a) What is
the amplitude of the block's motion? (b) What is its period? (c)
How long after release does the block take to first return to its
equilibrium position? (d) What is its speed at that position? {b.
3.43 s, d. 1.38 m/s}
a) A=0.753m
b)...

A spring-mass system consists of a 0.5 kg mass attached to a
spring with a force constant of k = 8 N/m. You may neglect the mass
of the spring. The system undergoes simple harmonic motion with an
amplitude of 5 cm. Calculate the following: 1. The period T of the
motion 2. The maximum speed Vmax 3. The speed of the object when it
is at x = 3.5 cm from the equilibrium position. 4. The total energy
E...
