Question

A spring with a force constant of 3x10^3 Nm-1 is used to measure the mass of an object. If the spring extends by 5cm when the object is hung from it, the mass of the object is

Answer 1

15.29 kg

Step-by-step explanation:

F = k * d 5cm = .05 m

= 3 x 10^3 n/m * .05 m = 150 N

= 150 kg -m / s^2

150 kg- m / s^2 / 9.81 m/s^2 =15.29kg
