Question

un movil parte del reposo con una aceleracion de 0,4 m/seg2 calcular a los 2 seg a) la distancia recorrida b) la rapidez

Answer 1

Vo = 0
a = 0.4m/s²
t = 2s
d =?
Vf =?

d = Vot + at²/2
d = 0 + 0.4m/s² ×(2s)²/2
d = 0.4m/s²×4s²/2
d = 0.4m/s² ×4s²
d = 1.6m

Vf = Vo + at
Vf = 0 + 0.4m/s²×2s
Vf = 0.8m/s

Answer 2

Respuesta:

Vo = 0

a = 0.4m/s²

t = 2s

d =?

Vf =?

d = Vot + at²/2

d = 0 + 0.4m/s² ×(2s)²/2

d = 0.4m/s²×4s²/2

d = 0.4m/s² ×4s²

d = 1.6m

Vf = Vo + at

Vf = 0 + 0.4m/s²×2s

Vf = 0.8m/s
