Answer:
Hire, organize, and supply workers.
Explanation:
The answer is C 300,000 kilometers per second
Answer:
The correct option is b: 30 N.
Explanation:
First, we need to find the acceleration due to gravity (a):
(1)
Where:
: is the final vertical position (obtained from the graph)
: is the initial vertical position (obtained from the graph)
v₀: is the initial speed = 0 (it is released from rest)
Δt: is the variation of time (from the graph)
From the graph, we can take the following values of height and time:
t₀ = 0 s → = 5 s
y₀ = 300 m → = 225 m
Now, by entering the above values into equation (1) and solving for "a" we have:
Finally, the weight of the object is:
Therefore, the correct option is b: 30 N.
I hope it helps you!
