Explicación:
Fr: Fuerza resultante
m: masa
a: aceleración
60 = 3.a
a = 20 [tex]m/s^{2}[/tex]
12. F = 2.20
F = 40 N
13. 100 = m.20
m = 5 kg
14. 50 = m.4
m = 12,5
⇒ 25 = (12,5)(a)
a = 2 [tex]m/s^{2}[/tex]
18. Fórmula del MRU, si la velocidad aumenta:
[tex]V_{f} =V_{o} + a.t[/tex]
13 = 3 + a.2
a = [tex]5 m/s^{2}[/tex]
F = 7.5
F = 35N
