Answer:
U = 11.85 J
Step-by-step explanation:
given,
spring is stretched = 23 cm
x = 0.23 m
Force experiences = 103 N
we know,
F = k x
where k is the spring constant
k = 447.83 N/m
energy stored in the spring
![U =(1)/(2)kx^2](https://img.qammunity.org/2021/formulas/physics/college/9ujhfg6r8ogvjhofh7dnsba2rjku78vpft.png)
![U =(1)/(2)* 447.83 * 0.23^2](https://img.qammunity.org/2021/formulas/physics/college/3hhy6qa8u3r7juheo4gzzo6hqyzx2mjyga.png)
U = 11.85 J
hence, energy stored in the spring is equal to U = 11.85 J
