The equation of the motion of a body suspended by a spring is T=2π√m/k, where T is the time period, m is the mass of the body, and k is the force constant of spring. use this information to find the time period if a body of mass 10 kg is suspended by a spring of force constant 1400 Nm^-1. Round to the nearest tenth.

Question

My answer: I did not exactly complete the problem as I am unsure if these values belong there; T=2π√10/1400, is this the correct step or was I supposed to convert the nanometers to a different unit?

Thank You

Answer 1

Nm-1 is not nanometers, it is force/distance or N/m
remember hookes law
F=kx or k=force/distance=N/m
