Question 4

The spring constant of a spring is 50 N/m.

The spring is stretched so that its extension is 8.0 cm.

Calculate the elastic potential energy stored in the spring.

Use the equation:

elastic potential energy=0.5×spring constant×(extension)2 \text{elastic potential energy} = 0.5 \times \text{spring constant} \times (\text{extension})^2 elastic potential energy=0.5×spring constant×(extension)2
