Answer:
u are falling
Explanation:
In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.
A carpenter hammering a nail
Explanation:
This is the only choice that gives you an object exerting a force ( the carpenter/hammer ) and one that has a force exerted on it ( the bail )
All of the rest would be related to acceleration and speed
Answer:
-4m/s²
Explanation:
a = Δv/t
Our change in velocity is equal to v₂-v₁, which in this equation is 0 m/s - 100 m/s, so our change in velocity is -100m/s. Now plug that and our time into the equation, like so:
a = (-100m/s)/(25s) a= -4m/s².
