Answer:
The correct answer is C
Explanation:
Change is momentum can be described as the change in the product of mass and velocity of a body. Every moving object as a momentum and the higher the momentum of this object, the harder it is to stop. Impulse (a force), which is sometimes used to describe change in momentum can be described as the product as force multiplied by time.
From the description above, it can be deduced that an increase in impulse can lead to a greater change in momentum. And an increase in impulse can be brought about by an increase in the time it takes a body to be brought to rest after collision. And since the car that hit the water barrels was brought to rest at a longer time, it has a greater change in momentum
Answer:
-5 m/s^2
Explanation:
10/2=5 and is is a stop so it is negitive

Answer:
Conociendo la velocidad inicial del proyectil y el angulo de lanzamiento con respecto ala horizontal.
Explanation:
Para poder anticipar la caída del proyectil es importante conocer la velocidad inicial del proyectil y el angulo de disparo del proyectil con respecto a la horizontal.
A continuación se presenta un diagrama o esquema donde se pueden ver estas variables y se explicaran a la brevedad:
Para poder encontrar el rango que es la máxima distancia horizontal recorrida por el proyectil debemos utilizar la siguiente ecuación:
![x=(v_{o})_{x} *t\\where:\\(v_{o})_{x} = velocidad inicial x-component [m/s]\\t= time [s]](https://tex.z-dn.net/?f=x%3D%28v_%7Bo%7D%29_%7Bx%7D%20%2At%5C%5Cwhere%3A%5C%5C%28v_%7Bo%7D%29_%7Bx%7D%20%3D%20velocidad%20inicial%20%20x-component%20%5Bm%2Fs%5D%5C%5Ct%3D%20time%20%5Bs%5D)
Para poder encontrar el tiempo debemos utilizar la siguiente ecuación:
![y=(v_{y} )_{o}*t-0.5*g*t^{2} \\donde:\\(v_{y} )_{o}= velocidad inicial componente y [m/s]\\g = gravity = 9.81 [m/s^2]\\t = time [s]](https://tex.z-dn.net/?f=y%3D%28v_%7By%7D%20%29_%7Bo%7D%2At-0.5%2Ag%2At%5E%7B2%7D%20%20%5C%5Cdonde%3A%5C%5C%28v_%7By%7D%20%29_%7Bo%7D%3D%20velocidad%20inicial%20componente%20y%20%5Bm%2Fs%5D%5C%5Cg%20%3D%20gravity%20%3D%209.81%20%5Bm%2Fs%5E2%5D%5C%5Ct%20%3D%20time%20%5Bs%5D)
En la anterior ecuación, igualamos y = 0, ya que cuando el proyectil cae al suelo la distancia vertical es cero. De esta manera podemos encontrar el tiempo t, ya que conocemos la velocidad inicial del proyectil en la componente y.
Seguidamente reemplazamos t en la primera ecuacion y encontramos la distancia x o el rango.
Transpiration is the evaporation of water from plants. This occurs when water drawn from the roots is brought up the leaves (as it usually should), and, because of the outside heat, it vaporizes and exits via the pores found on the underside of the leaves.
