a) 2,0.10^4
b) 2,6.10^4
c) 3,0.10^4
d) 2,0.10^3
e) 3,0.10^3
Dados :
m = 2000 kg
v = 30 m/s
R = 300 m
g = 10 m/s²
N = ?
Resolução
N - P =Fc
N = Fc + P
N = m*v²/R + m*g
N = 2000*30²/2 + 2000*10
N = 26000 = 2,6*10^4 N
Letra B
N = Fc + P
N = m*v²/R + m*g
N = 2000*30²/2 + 2000*10
N = 26000 = 2,6*10^4 N
Letra B
