1. your new designer chair has an s-shaped tubular metal frame that behaves just like a spring. when your friend, who weighs 600 n, sits on the chair, it bends downward 4 cm. what is the spring constant for this chair?

Explanation:

Given that,

Weight of the friend, W = 600 N

When the friend sits on the metal frame it bends downward 4 cm, we can say that the compression in the it is 4 cm or 0.04 m

To find,

Spring constant for this chair or k

Solve :

The weight of an object is equal to the force exerted by the gravitational force, F = 600 N

According to Hooke's law, the force exerted by the spring is given by :

F = kx

k is the spring constant

k = 15000 N/m

Therefore, the spring constant of the spring is 15000 N/m.

your answer is, orbit around the nucleus
