Question 16
F

A spring has a spring constant of 40 N/m. The spring is stretched by 10 cm.

Use the equation: energy transferred in stretching=0.5×spring constant×(extension)2\text{energy transferred in stretching} = 0.5 \times \text{spring constant} \times (\text{extension})^2energy transferred in stretching=0.5×spring constant×(extension)2

How much energy is transferred to the spring?
