Answer:
x= 80 cm : Spring stretch
Explanation:
Hooke's law:
The force applied to a spring is proportional to the spring stretching:
F=K*x (Formula (1)
Where:
F=Force applied to the spring (N)
K= spring elasticity constant (N/m)
x= spring stretch (m)
Known data
F=520 N
k=650 N/m
Problem development
We apply formula (1) for calculate the spring strech (x):
F=K*x
520N=(650 N/m) *x
x= (520N) / (650 N/m)
x= 0.8 m = 0.8m* 100cm/m = 80cm
x= 80 cm
