Respuesta:
W= 192793.2 Joules
P= 48198.3 Watts o vatios
Explicación:
m= 500 kg
vo=0
vf = 100 km/h =27.77 m/s
t= 4seg
W=?
P=?
vf - vo 27.77 m/s - 0
a= --------------- = ------------------------ = 6.94 m/s²
t 4 seg
vf² - vo² (27.77 m/s)² - 0
d = --------------- = ------------------------ = 55.56 m
2a 2(6.94 m/s²)
F= ma
F= 500 kg x 6.94 m/s²
F= 3470 N
W= F x d
W = 3470 N x 55.56 m
P= W/t
P = 192793.2 Joules / 4seg
Bueno espero haberte ayudado, saludos desde Guayaquil_Ecuador
