A Hooke's law spring constant k=7 220 N/m is compressed 12.0 cm from equilibrium using a 1 kg mass starts to move up on a frictionless inclined plane. Find the velocity immediately after it is released. Find its potential energy as it moves up 3 meters.
A light spring has unstressed length 15.7 cm. It is described by Hooke's law with spring constant 4.31 N/m. One end of the horizontal spring is held on a fixed vertical axle, and the other end is attached to a puck of mass m that can move without friction over a horizontal surface. The puck is set into motion in a circle with a period of 1.43 s. (a) Find the extension of the spring x as it depends on...

A mass m = 1.1 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 75 N/m and negligible mass. At time t = 0 the mass is released from rest at a distance d = 0.35 m below its equilibrium height and undergoes simple harmonic motion with its position given as a function of time by y(t) = A cos(wt - φ). The positive y-axis...
A pogo stick has a spring with a force constant of 2.50 × 104 N/m , which can be compressed 12 cm. To what maximum height, in meters above the compressed position of the spring, can a child jump with the stick using only the maximum elastic potential energy in the spring, if the child and stick have a combined mass of 35 kg?
Suppose a force of 40 N is required to stretch and hold a spring 0.1 m from its equilibrium position. a. Assuming the spring obeys Hooke's law, find the spring constant k. b.

please fill out the table with explanation EXPERIMENT #12 HOOKE'S LAW AND SPRING DEFORMATION EXPERIMENT A measurement of mass(kg) attached to an extensible spring were conducted and recorded. Initially a mass in kg was attached to the spring, and the corresponding extension was measure with a meter stick recorded. Subsequent masses were added to mass already hanging on the spring and the table below was computed to give stress (Pa), and strain of the experiment. DATA FROM THE EXPERIMENT COPPER...
please help! this is a fluids question in physics. 1-3 (a) What is the height of a fluid column in a barometer that uses water as its 5 pts fluid in 0.924 atm of air pressure? The density of water is 1000 kg/m'. Neglect the vapor pressure in the apparently empty space above the column. Use g = 9.80 m/s² and give the height in meters. m( + 0.02 m) (b) What is the height if the fluid is mercury?...
A brick of mass m=0.49 kg is set against a spring with a spring constant of k1 = 639 N/m which has been compressed by a distance of 0.1 m. Some distance in front of it, along a frictionless surface, is another spring with a spring constant of k2 = 261 N/m. Part (a) How far, d2 in meters, will the second spring compress when the brick runs into it? Part (b) How fast, v in meters per second, will the brick...
please solve both. thank you! A mass of 1.25 kg stretches a spring 0.06 m. The mass is in a medium that exerts a viscous resistance of 56 N when the mass has a velocity of 2 . The viscous resistance is proportional to the speed of the object. Suppose the object is displaced an additional 0.03 m and released. Find an function to express the object's displacement from the spring's equilibrium position, in m after t seconds. Let positive...
