A 10. kg mass, hung onto a spring, causes the spring to stretch 2.0 cm. The spring constant is

Question

Quizplus · Accepted Answer

The spring constant (k) can be calculated using Hooke's Law, F = kx, where F is the force applied (in this case, the weight of the mass, which is mass * gravity = 10kg * 9.8m/s^2 = 98N) and x is the displacement (2.0cm = 0.02m). Rearranging the formula to solve for k gives k = F/x. However, since the answer is in N/cm, we should use the displacement in cm, so k = 98N / 2.0cm = 49 N/cm.
