A pogo stick has a spring with a force constant of 2.50 × 104 N/m , which can be compressed 12.4 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 36 kg?

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?
A 25 kg child bounces on a pogo stick. The pogo stick has a spring with spring constant 2.0x10^4 N/m. When the child makes a nice big bounce, he finds that at the bottom of the bounce he is accelerating upwards at 9.8 m/s^2. How much is the spring compressed?
A 30 kg child uses a pogo stick to bounce up and down. The spring constant, k, of the toy equals 8,900 N/m. (a) By how much would the spring be compressed by the child if she simply balanced herself vertically on the pedals of the stick? (Give your answer in cm.) ________ cm (b) How much energy (in J) is stored in the spring under this circumstance? __________J
2 pts A toy manufacturer wishes to design a pogo stick so that when a child of mass 44.0 kg compresses the spring of the stick by 13.5 cm, the maximum height reached by the child is 28.4 cm. What spring constant should the manufacturer use? (Assume that mass of the stick is small compared to the child.)
When an 60.2 kg man stands on a pogo stick, the spring is compressed 0.107 m. What is the force constant of the spring?
A spring of negligible mass has force constant k = 1500 N/m. How far must the spring be compressed for an amount 3.40 J of potential energy to be stored in it? You place the spring vertically with one end on the floor. You then drop a book of mass 1.30 kg onto it from a height of 0.700 m above the top of the spring. Find the maximum distance the spring will be compressed.
Problem 2 A spring of negligible mass has force constant k = 2500 N/m. a) How far must the spring be compressed for an amount 5.0 J of potential energy to be stored in it? b) You place the spring vertically with one end on the floor. You then drop a book of mass 2.0 kg onto it from a height of 0.800 m above the top of the spring. Find the maximum distance the spring will be compressed.
A 65.0-g object connected to a spring with a force constant of 40.0 N/m oscillates with an amplitude of 5.00 cm on a frictionless, horizontal surface (a) Find the total energy of the system. We know the spring constant and the maximum displacement of the object. What is the value of the spring potential energy and the kinetic energy at that instant? mJ (b) Find the speed of the object when its position is 1.10 cm. (Let 0 cm be...
