how much force is needed to stretch a spring 1.2 m if the spring constant is 8.5 n/m?\n7.1 n\n7.3 n\n9.7 n\n10.2 n
Answer
Explanation:
Step1: Identify the formula
Use Hooke's law $F = kx$, where $F$ is force, $k$ is spring - constant and $x$ is displacement.
Step2: Substitute values
Given $k = 8.5\ N/m$ and $x = 1.2\ m$. So $F=8.5\times1.2$.
Step3: Calculate the result
$F = 10.2\ N$.
Answer:
D. 10.2 N
