Acceleration points in the same direction as the net force, so to the left.
The direction of velocity can't be determined from this information alone, though. If the object is at rest, it will being moving to the left. If the object is already moving to the left, it will continue doing so and speed up. If it starts off moving to the right, it will continue to move to the right but eventually slow to a stop before starting to move to the left. There are more cases to consider if you're talking about motion in more than one dimension.
Answer & Explanation:
A provisional patent application, also called a PPA, shows your invention as being in the process of getting a patent. This means that you will be safe from others copying your idea while your patent application is still being processed.
La cinemática permite encontrar la respuesta para la aceleracion del cuerpo en el cañón es:
a = 1,8 10⁶ m/s²
La cinemática estudia el movimiento de los cuerpos, buscando relaciones entre la posicion, la velocidad y la aceleración.
v² = v₀² + 2 a x
Donde v y v₀ son la velocidad actual e inicial, respectivamente, a es la aceleracion y x la distancia recorrida.
Indica que la longitud de cañon es x= 18 m la velocidad de salida es
v= 29000 km/h (
) (
s) = 8,055,56 m/s.
La velocidad inicial del proyectil es cero.
a =
a =
a = 1,8 10⁶ m/s²
En conclusión usando la cinemática podemos encontrarla respuesta para la aceleracion del cuerpo en el cañón es:
a = 1,8 10⁶ m/s²

Answer:
Time, t = 2 seconds
Explanation:
Given the following data;
Mass, m = 50 kg
Initial velocity, u = 0 m/s (since it's starting from rest).
Final velocity, v = 8 m/s
Force, F = 200 N
To find the time, we would use the following formula;

Making time, t the subject of formula, we have;

Substituting into the formula, we have;



Time, t = 2 seconds
