Answer:
Explanation:
Given
Weight of Person 
Cave is 
deep
Breaking stress 
Net Force on Person
The shortest time such that the person can be taken out of cave
where
h=distance moved
t=time
a=acceleration
Answer:
Paramedic
Explanation:
They will be on the move the whole time
5 seconds is a poor time to ask about, because the speed abruptly changes at exactly 5 seconds.
Up until that time, the speed has been 1 m/s. And then, at exactly 5 seconds, it becomes zero.
_________
It's also a poor question because speed is calculated from the distance covered, but the graph shows displacement, not distance. You can't really tell the distance covered from a displacement graph.
For example, if an object happens to be moving in a circle around the place where it started, then the total distance covered keeps increasing, but its displacement is constant.
For this specific problem, the photons have been localized to
D<span>x = </span>0.027m
uncertainty. I am hoping that this answer has satisfied your
query about and it will be able to help you, and if you’d like, feel free to
ask another question.
Answer:
160N/m
Explanation:
According to Hooke's law which states that the extension of an elastic material is directly proportional to the applied force provided that the elastic limit is not exceeded. Mathematically,
F = ke where
F is the applied force
k is the spring constant
e is the extension
From the formula k = F/e
Since the body accelerates when the block is released, F = ma according to Newton's second law of motion.
The spring constant k = ma/e where
m is the mass of the block = 0.4kg
a is the acceleration = 8.0m/s²
e is the extension of the spring = 2.0cm = 0.02m
K = 0.4×8/0.02
K = 3.2/0.02
K = 160N/m
The spring constant of the spring is therefore 160N/m
