Answer:
a) 
b) imagen adjunta
Explanation:
a) Primero debemos hacer la conversión de 81 km/h a m/s, esto es 22.5 m/s.
Ahora, usando la ecuacion cinemática, en un movimiento acelerado tenemos:

Queremos encontrar la posición hasta detenerse, osea vf = 0.



b) Para este caso el gráfico se encuentra adjunto.
Espero que te sirva de ayuda!

Answer:
V = 156.13 [cm³]
Explanation:
El volumen de un solido con forma de paralepipedo se puede calcular por medio de la siguiente formula:

donde:
V = volumen [cm³]
ancho = 3.4 [cm]
largo = 11.2 [cm]
alto = 4.1 [cm]
Ahora reemplazando.
![V = 3.4*11.2*4.1\\V = 156.13 [cm^{3}]](https://tex.z-dn.net/?f=V%20%3D%203.4%2A11.2%2A4.1%5C%5CV%20%3D%20156.13%20%5Bcm%5E%7B3%7D%5D)
The normal force acts to counter the gravitational force, that is the upward direction.
<span>Most low-level radioactive waste (LLW) is typically sent to land-based disposal immediately following its packaging for long-term management. This means that for the majority (~90% by volume) of all of the waste types produced by nuclear technologies, a satisfactory disposal means has been developed and is being implemented around the world.
</span>
Radioactive wastes are stored so as to avoid any chance of radiation exposure to people, or any pollution.The radioactivity of the wastes decays with time, providing a strong incentive to store high-level waste for about 50 years before disposal.Disposal of low-level waste is straightforward and can be undertaken safely almost anywhere.Storage of used fuel is normally under water for at least five years and then often in dry storage.<span>Deep geological disposal is widely agreed to be the best solution for final disposal of the most radioactive waste produced.
