Question

A spring has a spring constant of 100 N/m. What is the mass of an object if spring stretches 10.0 cm

Answer 1

Answer:

Mass of the object will be 1.020 kg

Explanation:

We have given spring constant K = 100 N/m

Spring stretches to a length of 10 cm

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

So x = 0.1 m

Spring force will be given by $F=Kx$

This force will be equal to weight of the object

So $mg=kx$

So $m=\frac{Kx}{g}=\frac{100\times 0.1}{9.8}=1.020kg$

So mass of the object will be 1.020 kg
