The height (m) of a spring over time, in seconds, can be modeled by the function h(t) = 3cos3t + 3 over the interval t e [0, 71]. a) At what time(s) does the spring change direction? b) What is the spring's maximum velocity?

A 0.48 kg block is attached to a spring with a spring constant 0.69 N/m.  Both the spring and the block are placed on a frictionless horizontal surface.  The spring is then extended to be 0.42m longer than its relaxed length, and is released.  What is the position of the block 3.05 seconds later?

A spring is suspended from a support and a meter stick is placed next to the spring. Different masses are hung from the bottom of the spring and the length of the spring stretch is recorded. Which is the independent (manipulated) variable in this investigation? O the kind of spring O the type of support O the amount of mass O the type of meter stick ell 5 g 10 g 20 g

Chapter 16: Problem 5: The device pictured in the figure entertains infants while keeping them from wandering. The child bounces in a harness, with a spring constant k, and is suspended off of the ground. a) If the spring stretches x1 = 0.255 m from equilibrium while supporting an 7.6-kg child, what is its spring constant, in newtons per meter?  b) What is the time, in seconds, for one complete bounce of this child about the point x1?  c) What is the child’s maximum velocity, in meters per second, if the amplitude of her bounce, relative to x1, is 0.205 m?

ALSO...the solution is not 453.6238. Someone previously here gave me this answer and it is incorrect.

A spring in a toy gun has a spring constant of 9.80 N/m and can be compressed 20.0 cm beyond the equilibrium position. A 1.00 - g pellet resting against the spring is propelled forward when the spring is released. (a)  Find the muzzle speed of the pellet. (b) If the pellet is fired horizontally from a height of 1.00 m above the floor, what is its range?

Multiple-Concept Example 6 reviews the principles that play a role in this problem. A bungee jumper, whose mass is 70 kg, jumps from a tall building. After reaching his lowest point, he continues to ocillate up and down, reaching the low point two more times in 9.3 s. Ignoring air resistance and assuming that the bungee cord is an ideal spring, determine its spring constant.

The spaceship Intergalactica lands on the surface of the uninhabited Pink Planet, which orbits a rather average star in the dista Garbanzo Galaxy. A scouting party sets out to explore. The party's leader—a physicist, naturally—immediately makes a determination of the acceleration due to gravity gpp on the Pink Planet's surface by means of a simple pendulum of length 1.30 m. She sets the pendulum swinging, and her collaborators carefully count 110 complete cycles of oscillation during 205 What does the party measure for gpp for the Pink Planet? gpp = m

A 0.282 kg mass is attached to a spring with a spring constant 197 N/m so that the mass is allowed to move on a horizontal frictionless surface. The mass is released from rest when the spring is compressed 0.145 m. Find the maximum force on the mass. Answer in units of N.
