We have that the Number of stitches per sec and he mass of  oscillation motion is mathematically given as

a) Nt=25stitches per sec

b) m=2.033e-5kg

Number of stitches per sec and he mass of  oscillation motion

Question Parameters:

This sewing machine is capable of stitching 1,500 stiches in one minute.

If the sewing machine has a spring constant of 0.5 N/m,

Generally the equation for the Number of stitches per sec  is mathematically given as

Nt=N/t

Therefore

Nt=1500/60

Nt=25stitches per sec

b)

Generally the equation for the Time t  is mathematically given as

[tex]T=2\pi\sqrt{\frac{m}{k}}[/tex]

Therefore

[tex]0.04=2\pi\sqrt{\frac{m}{0.5}}\\\\m=\frac{0.5*0.04^2}{4\pi^2}[/tex]

m=2.033e-5kg
