the answer says its 140 N/m but i cannot get that answer i am using
t=2(pi)vm/k
.75=6.28v(.15/k)
.0143=.5/k

A mass of 1.89 kg on a spring rests on a frictionless surface and has a horizontal force of magnitude 1.7 N applied to it to keep it 1.57 m from the equilibrium. The mass undergoes simple harmonic motion when released.

Spring constant = 1.08 N/m
Frequency = 0.120 Hz
Maximum speed = 1.19 m/s

What is the maximum magnitude of the acceleration?

What is the magnitude of the acceleration of the mass when it's displacement is one fifth of the maximum value?
