23. A pogo stick has a spring with a force constant of 2.50×104N/m , which can be compressed 12.0 cm. To what maximum height can
tensa zangetsu [6.8K]

Answer:

The maximum height the child can jump on the stick

h=0.459m

Explanation:

Energy conservation

Energy kinetic = Work

The energy the child do get the height jump is proportional at the distance and the consta can be compressed so:

\frac{1}{2}*k*x^{2} =m*g*h\\k=2.50x10^{4} \frac{N}{m}\\x=12cm*\frac{1m}{100cm}=0.12m\\h=\frac{k*x^{2} }{2*m*g}\\h=\frac{2.50x10^{4}\frac{N}{m}*(0.12m)^{2} }{2*40kg*9.8\frac{m}{s^{2}}}\\h=\frac{360\frac{N}{m}m^{2} }{784N}\\h=0.459m

Which of the following is an example of qualitative data
NemiM [27]
Qualitative data is easy to explain. You either agree or disagree in writing. Wrong. You agree, disagree, or qualify. Meaning agree to somewhat extend, but not entirely. So you can agree that people should walk instead of talk in the progressive manner, but not in the impulsive manner.
