Answer:
F= 129.6 N ≈ 130 N
Step-by-step explanation:
According to Hook's Law:
F = kx
F = Force necessary to stretch the spring
k = spring constant
x = displacement of the spring (stretch in the spring), in meters
Given x = 48 cm = 0.48 m
k = 270 N/m
F = kx
F = (270 N/m)(0.48 m) = 129.6 N
F = 129.6 N ≈ 130 N
