Answer:

h = 65.021 m

Explanation:

Given that,

Initial velocity of a baseball, u = 17 m/s

It lands 2.3 seconds later.

We need to find the height of the building. Let it is h. It can be calculated using second equation of motion as follows :

h=ut+\dfrac{1}{2}at^2

here, a = g

h=17(2.3)+\dfrac{1}{2}\times 9.8\times 2.3^2\\\\=65.021\ m

So, the building is 65.021 m tall.

Nesterboy [21]

Answer:

0.741\ \text{m/s}^2

Explanation:

v = Velocidad final = 40\ \text{km/h}=\dfrac{40}{3.6}\ \text{m/s}

u = Velocidad inicial = 0

t = Tiempo empleado = 15 s

a = Aceleración

De las ecuaciones cinemáticas tenemos

v=u+at\\\Rightarrow a=\dfrac{v-u}{t}\\\Rightarrow a=\dfrac{\dfrac{40}{3.6}-0}{15}\\\Rightarrow a=0.741\ \text{m/s}^2

La aceleración del camión en el primer intervalo de tiempo es 0.741\ \text{m/s}^2.
