55.88391 N/m
Explanation:
m = Mass of person = 58.5 kg
T = Time period =
k = Spring constant
g = Acceleration due to gravity = 9.81 m/s²
Time period is given by
The spring stiffness constant is 55.88391 N/m
The force on spring is given by
The unstreched length of the cord is 20.5-10.26923 = 10.23077 m

Explanation:
The initial speed of the circular saw is:
Deceleration rate needed to stop the circular saw is:
The number of turns associated with such deceleration rate is:
Since the measured number of revolutions is lesser than calculated number of revolution, the circular saw meets specifications.
