Explicación:
Ejercicio 1:
Ep =?
k = 400 N/m
x = 80 cm = 0.8 m
Ep = 0.5 K x²
Ep = 0.5 (400 N/m) (0.8 m)²
Ep = 128 Joules
Ejercicio 2:
K = 160 N/m
Ep = 300 J
x =?
Ep
----------- = x²
0.5 K
300 J
--------------------- = x²
0.5(160 N/m)
3.75 m = x²
√3.75m = √x²
1.93 m = x
Ejercicio 3:
Ep = 800 J
x = 1 m
K=?
--------- = K
0.5 x²
800 J
0.5 (1)²
1600 N/m = K
Ejercicio 4:
Ep = 0.5 (200 N/m) ( 0.5m)²
EP = 25 Joules
