A car hit a speedbump and bounces at a frequency of 3 Hz. If the car has a mass of 600 kg, then how strong is the spring in the car’s suspension?

Respuesta :

Answer:

2.13 x 10^5 N/m

Explanation:

Use two formulas, T=1/f and T=2π [tex]\sqrt{\frac{m}{k} }[/tex]

T=1/3

Plug in Time and mass into this formula

T=2π [tex]\sqrt{\frac{m}{k} }[/tex]

1/3=2 [tex]\sqrt{\frac{600}{k} }[/tex]  

K= 2.13 x 10^5 N/m
