[tex]\boxed{(Energia\ cinetica)=1/2(masa)(velocidad^{2} )}[/tex]
E.N = (1/2)(40)(3²)
E.N = (20)(9)
→ E.N = 180 J
E.N = (1/2)(4)(2²)
E.N = (2)(4)
→ E.N = 8 J
E.N = (1/2)(masa)(velocidad²)
24 = (1/2)(3)(velocidad²)
48 = (3)(velocidad²)
16 = (velocidad²)
→ 4 m/s = velocidad
7,2 km/h.(5/18) = 2 m/s
E.N = (1/2)(5)(2²) ( Creo que hubo un error en el número dentro del bloqe )
E.N = (1/2)(4)(5)
E.N = (2)(5)
→ E.N = 10 J

400g.(1/1000) = 0,4 kg
E.N = (1/2)(0,4)(10²)
E.N = (0,2)(100)
→ E.N = 20 J
Vo = 0 m/s ( al momento de soltarla )
Vf: Velocidad final luego de 2 segundos.
t = 2
g = 10 m/s²
Vf = 0 + 10(2)
Vf = 20 m/s ( velocidad después de 2 segundos )
E.N = (1/2)(1)(20²)
E.N = (1/2)(400)
→ E.N = 200 J

Dados los conjuntos:
A = {- 2; 5; 7}
B = {1 ; 3}
Calcula M: n(A) + n(b) ÷ n(A x B ) + n(B x A)
