What are the options?
i took physics last year and the first thing that came to mind was the forces that make a plane fly: drag, gravity, push, and lift.
Answer:
F₁ = F₂
Explanation:
Given that
floor pushing up on you by force F₁
gravity pulling down by force F₂
From second law of Newton's
F₁ - F₂ = m a
But here given that ,elevator is moving with constant speed .It means that acceleration of the elevator is zero.
a= 0 m/s²
F₁ - F₂ = m x 0
F₁ = F₂
Answer:
2.45s
Explanation:
is explanation needed too?
Answer:
6 m/s²
Explanation:
From the question given above, the following data were obtained:
Velocity (v) = 30 m/s
Time (t) = 5 s
Acceleration (a) =..?
Acceleration is defined mathematically as:
Acceleration (a) = Velocity (v) /time (t)
a = v /t
With the above formula, we can obtain the acceleration of the object as follow:
Velocity (v) = 30 m/s
Time (t) = 5 s
Acceleration (a) =..?
a= v/t
a= 30/5
a = 6 m/s²
Therefore, the acceleration of the object is 6 m/s² due East.
