A= v²/R
a = 12²/30 =4.8 m/s²
Answer:
a = 3,0 m/s²
Explanation:
En este ejercicio se pide calcular la aceleracion del cuerpo, usemos las ecuaciones de cinematica en una dimensión.
v= v₀ + a t
como el corredor parte del reposo si velocidad inicial es cero
v = at
a = v/t
calculemos
a = 12 /4,0
a = 3,0 m/s²
When two oceanic plates meet, the process of subduction occurs. During this, the denser plate slips underneath the lighter one, creating a subduction zone. In these subduction zones, a trench is formed.
Trenches are deep crevices on the ocean floor and are home to many different marine species.<span />
You take 3 steps east, turn around & take another 7 steps west (4 steps always from origin) you turn around again and take 6 more steps east - 2 steps always from origin
Newton's second law of motion states that the force is equal to the product of the mass and acceleration. It can mathematically be expressed as,
F = m x a
When this equation is transformed to solve for acceleration, this becomes,
a = F / m
The equation suggests that for an object to move, force has to be exerted.
