Question

what is the magnitude of the force required to stretch two springs of constants 100N/m and 300N/m by 6 cm, if they are in series.?
plss provide a explained answer!!​

Answer 1

Explanation:

The two springs behave like a spring with constant k obtained by solving for k the following

1 / k = 1 / 100 + 1 / 300

k = 75 N / m

| F | = k | Δx | = 75 N / m × 0.06 m = 4.5 N
