Question

un motor de 120 cv es capaz de levantar un bulto de 2 ton hasta 25m

Answer 1

Explicación

P = 120 cv
m = 2 Ton
h = 25 m
P = F = m g =(2000 kg) (10 m/s²) = 500000 N
T = F h =( 500000 N)(25 m) = 12500000 Joule
P = 120 CV (736 W / 1 CV) = 88320 W
t = T / P = 12500000 Joule / 88320 W = 141.53 s

Answer 2

Respuesta:

t = 5,661 segundos

Explicación:

W = F*h

W = m*g*h

P = W/t ==; t = W/P

t = (m*g*h)/P

P = 120 cv * 746 W/vc

= 88320 W

t = (2000*9,81*25)/88320

t = 5,661s
