Mr. Rosario has created a catapult so that he can fling any of his misbehaving students out of his classroom. He finally tests out this catapult and his student gets flung a total of 500 meters straight up into the air! It the student weighed 77 kg and the band he used for the catapult was pulled back 3 meters, what is the rubber bands k constant?

Respuesta :

For this we are going to neglect the losses

[tex]\begin{gathered} 77kg\cdot\frac{9.81m}{s^2}\cdot500m=\frac{1}{2}k\cdot(3m)^2 \\ 77¨9.81\cdot500\cdot\frac{2}{9}=\frac{83930N}{m} \end{gathered}[/tex]
