Wewaii [24]
Imagine fractions as a pie. The bottom number is the total pieces of slices that make up the pie. The top number is how many you are served.

If there are a total of 5 pieces and you get 3 pieces of the pie, is that larger than getting 1 piece of the pie? Yes!

A car moving at a constant speed passed a timing device at t = 0. After 8 seconds, the car has traveled 936 ft. Write a linear f
Ahat [919]

Answer:

Buenos días;

1) La ecuación de la velocidad en un movimiento uniformemente acelerado (M.U.A) es:

V=V₀+at.

V=30 m/s-2 m/s².t

Ahora elimina las unidades (m/s, m/s₂), y tendrás la ecuación de la velocidad en función del tiempo.  

V(t)=30-2t.

Sol: la ecuación de la velocidad en función del tiempo es : V(t)=30-2t.

2) La ecuación de la posición en función del tiempo en un M.U.A  es:

X=X₀+V₀.t+(1/2).a.t²

X=0+30 m/s.t+(1/2).(-2 m/s²).t²

Eliminas las unidades, y tendrás la ecuación de la posición en función del tiempo.

X(t)=30.t-t².

Sol: la ecuación de la posición en función del tiempo es: X(t):30t-t²

Un saludo.
