Question

Doy corona quien lo haga​

Answer 1

Respuesta:

T= 20seg

V.= 80km/h

Vf= 120km/h

A= 0.555m/seg²

80km/h x 1.000m/1km x 1h/3.600seg = 80 x 1.000m x 1/1 x 3.600seg = 80.000m/3.600seg= 22.2m/seg

120km/h x 1.000m/1km x 1h/3.600seg = 120 x 1.000m x 1/1 x 3.600seg = 120.000m/3.600seg = 33.3m/seg

A= 33.3m/seg - 22.2m/seg /20seg= 11.1m/seg /20seg = 0.555 m/seg²

espero q me entiendas
