A spring has a spring constant of 120 newtons per meter. Calculate the elastic potential energy stored in the spring when it is stretched 2.0 centimeters.

Respuesta :

The elastic potential of a spring can be calculated using the formula
E = (1/2) k x²
where are given that 
k = 120 N/m
the stretched length is
x = 0.02 m

The elastic potential is
E = (1/2) (120 N/m) (0.02 m)²
E = 0.024 N-m
