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?
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 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...
A 40.0 kg boy jumps on a 4.75 kg pogo stick with spring constant 3650 N/m. (a) Find the angular frequency. ? = rad/s (b) Find the frequency. f = Hz (c) Find the period of the boy's motion. T = s
The force constant of a spring is 550 N/m. How much elastic potential energy is stored in the spring if the spring is compressed a distance of 1.2 cm? What is the force being used to compress the spring?
The spring of a spring gun has force constant k = 450 N/m and negligible mass. The spring is compressed 6.40 cm and a ball with mass 0.0270 kg is placed in the horizontal barrel against the compressed spring. The spring is then released, and the ball is propelled out the barrel of the gun. The barrel is 6.40 cm long, so the ball leaves the barrel at the same point that it loses contact with the spring. The gun...
9. A spring with spring constant 8000 N/m sits vertically on a horizontally surface. The spring has an equilibrium length of 20 cm. A 3.0 kg ball is pushed down so that the spring is compressed by 12 cm and released from rest. You may neglect the effects of air resistance. eq. 20 cm 12 cm a. How much energy must you supply the system to compress the spring by 12 cm? Remember to include both gravitational and spring potential...
A massless spring of a spring gun has a force constant k=800 N/m. A ball of mass 0.5 kg is resting on top of the spring. The ball compresses the spring by d as shown in the right figure. When the gun is fired vertically, the ball reached a maximum height of 5 m from the top of the spring as it returns to its natural length. Calculate how much the spring was initially compressed (d). (a) 12 cm; (b)...
A spring has a force constant k=500 N/m. What is the elastic potential energy stored in it when (a) it is stretched 4.00 cm from equilibrium, (b) it is compressed 3.00 cm from equilibrium, and (c) it is unstretched?
