La velocidad \mathbf v del objeto al tiempo t es descrito por

\mathbf v(t)=v_x(t)\,\mathbf i+v_y(t)\,\mathbf j

donde

\begin{cases}v_x(t)={v_x}_0+a_xt\\v_y(t)={v_y}_0+a_yt\end{cases}

El objeto no tiene aceleración horizontal, pues a_x=0 y v_x está determinado exactamente por su velocidad inicial en la dirección horizontal. En la dirección vertical, la gravedad es la única fuerza que actúa en el objeto, pues a_y=-9.81\,\dfrac{\mathrm m}{\mathrm s^2}. Entonces, la velocidad después de 3\,\mathrm s satisface

{v_x}_0\,\mathbf i+\left({v_y}_0+\left(-9.81\,\dfrac{\mathrm m}{\mathrm s^2}\right)(3\,\mathrm s)\right)\,\mathbf j=20\,\mathbf i-4\,\mathbf j

Inmediatamente, vemos que {v_x}_0=20\,\dfrac{\mathrm m}{\mathrm s} y podemos encontrar que {v_y}_0=25.43\,\dfrac{\mathrm m}{\mathrm s}.

Su posicíon es descrita al tiempo t por

\mathbr r(t)=r_x\,\mathbf i+r_y\,\mathbf j

con

\begin{cases}r_x={r_0}_x+{v_0}_xt+\dfrac12a_xt^2\\\\r_y={r_0}_y+{v_0}_yt+\dfrac12a_yt^2\end{cases}

Si la posición inicial del objeto es el origen, suponemos que \mathbr r(0)=\mathbf 0, y además tenemos

\mathbf r(t)=\left(20\,\dfrac{\mathrm m}{\mathrm s}\right)t\,\mathbf i+\left(\left(25.43\,\dfrac{\mathrm m}{\mathrm s}\right)t+\dfrac12\left(-9.81\,\dfrac{\mathrm m}{\mathrm s^2}\right)t^2\right)\,\mathbf j

Queremos determinar el máximo de r_y. Encontramos que {r_y}_{\mathrm{max}}\approx32.9\,\mathrm m cuando t\approx2.59\,\mathrm s.

balandron [24]

Answer:

a. 45 N. / b. 0.08 m/s^2. / c. 102 N

F = ma

F = 15(3)

F = 45 newtons

F/m = a

20/250 = a

0.08 m/s^2 = a

R = ma

R =1.5(68)

102 N

When a "superball" is dropped, can it rebound to a<br> hightgreater than its origional hight?
Serhud [2]

Answer:

The superball cannot rebound to a higher height than its original height because that would go against the laws of energy conservation. For it to bounce higher than its original height, that means the potential energy acting on it is higher than the one it had been dropped with originally, and that energy must be an external one. However, it should be noted that if the superball is thrown downwards with an extra energy, then it can rebound higher than the original height.
