Respuesta:
Vf = 7 m/s
d= 51 m
Explicación:
a = 20 cm/s2 a = Vf-Vi / t Vf = (0.2*10) + 5
t = 10 s 0.2 m/s2 = Vf - 5 m/s / 10s Vf = 2 m/s + 5 m/s
Vi = 5 m/s 0.2 m/s2 (10 s / 1) = Vf - 5 m/s Vf = 7 m/s
(20 cm/1) (1 m / 100 cm) (1 / 1s2) a = 0.2 m/s2
d = Vi*t + 1/2 (a) (t)2
d = (5 m/s * 10 s) + 1/2 (0.2 m/s2) (10 s)2
d = 50 m + 1/ 2 (2 m)
d = 50 m + 1m d= 51 m
