Ejercicio 18
Datos:
m = 350 g
x = 10 cm = 0.1 m
k = 140 N/m
U elástica=?
U = 0.5 k x²
U = 0.5 ( 140 N/m)(0.1 m)²
U = 0.7 Joules
Ejercicio 20
d=?
F = 68 N
W = 120 J
W
------------------ = d
F
120 J
68 N
1.76 m = d
Ejercicio 21
t=?
P = 130 watts
W = 80 N
W 80 N
t = ------------ = ------------------- = 0.615 seg
P 130 watts
