Question

A 150kg person stands on a compression spring with spring constant 10, 000 N/m and norminal.Length of 0.50.What is the togal length of the loaded spring?

Answer 1

Total length of spring 0.647 m

Step-by-step explanation:

We have given mass of the person m = 150 kg

Acceleration due to gravity
`g=9.8m/sec^2`

Spring constant k = 10000 N/m

Nominal length of spring = 0.50

According to hook's law

`mg=kx`

`150* 9.8=10000* x`

x = 0.147 m

So total length of spring = 0.50+0.147 = 0.647 m
