13.An airplane starts from rest at the end of a runway and accelerates at a constant rate. In the first second, the airplane tra
Murrr4er [49]

Answer:

The answer is 3.33m

Explanation:

The acceleration "a" is constant.

Acceleration is the variation of velocity over time,

\frac{dv}{dt} = a.

solving the last equation

\int_{v_0}^v dv = a\int_0^t dt \rightarrow v-v_0 = at,

where v_0=0 because the airplane starts from rest.

Once again, velocity is the variation of distance over time.

\frac{dx}{dt} = at \rightarrow \int_{x_0}^x dx = a\int_0^t t\ dt

then

x- x_0 = \frac{1}{2}at^2

where x_0=0 if we consider  the end of the runway as the initial point (this step is for simplicity but you can let it expressed, it's going to cancel anyway).

If x=1.11\ m at t=1s, then

a = \frac{2x}{t^2} = 2.22\ m/s^2

and the final expression for the distance is

x = 1.11 t^2.

If t = 2s, x = 4.44 m. Which means thad the additional distance is

x(2s) - x(1s) = 4.44 - 1.11 = 3.33\ m

Se lanza un cuerpo de 25 kg sobre un plano horizontal, con una velocidad de 20 m/s. Si el coeficiente de rozamiento es de 0,4 ca
Alex Ar [27]

Answer:

1. 98 N

2. 51.0 m

Explanation:

masa 25 kg

velocidad 20 m/s

coeficiente de rozamiento .4

<u>Fuerza de rozamiento:</u>

mu * N, where mu = coeficiente de rozamiento, N = fuerza normal

Calcula N:

F = ma = 25 * -9.8 = -245 N

F rozamiento = mu * N = .4 * -245 = -98 N

<u>Espacio que recorrerá:</u>

F rozamiento = ma

-98 = 25a

a = -3.92 de-aceleración de la fuerza

vf = 0 m/s

vf = at + vi

0 = -3.92t + 20

t = 5.10 seg

x = 1/2 at^2 + vi*t

  = 1/2 * -3.92 * 5.10^2 + 20*5.10

  = 51.0 m
