Answer:
Explanation:
vi = 200/5 = 40 m/s
a = (vf - vi)/t = (60 - 40)/20 = 1 m/s²
F = ma = 2000(1) = 2000 N
Hi!
I think the answer is Brainstem. I hope this helps! :)
Answer:
y = constant
Explanation:
Bodies moving on the surface of Earth are subject to gravity, and they have a potential and kinetic energy. If there is no friction, the sum of the kinetic and potential energy remains constant.
Since potential energy depends on height, changes in altitude affect potential energy. Going higher increases this energy, this is accompanied by a reduction of kinetic energy and speed (since kinetic energy is related to speed). If the body goes down potential energy is reduced, but kinetic energy and speed increase.
For speed to remain constant the kinetic energy must remain constant. For the kinetic energy to remanin constant, the potential energy must remain constant, and for the potential energy to remain constant the height must remain constant.
I think it is D.) “Cycles around” but I am not positive.
Answer: The correct answer is 1800 meters
Explanation: The velocity is equal to distance over time. Thus the formula for distance is d=vt
And 1minute = 60 seconds
d= 30m/s×60s
d= 1800m
