Answer:
-40°C and -273°C ok do it
Answer:
Keep on moving
Explanation:
Newton's first law states "that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force."
Newton's Third Law of Motion states that springs exert a restoring force when they are pulled. The relationship between the spring force, spring constant, and spring displacement is governed by Hooke's Law.
Mass of the object= k*x/a= 26kg
what is Hooke's law?
The force (F) required to extend or compress a spring by a certain distance (x) scales linearly with respect to that distance, according to the empirical law known as Hooke's law.
according to Hooke's law
f=-k x (-ve because spring is compressing)
from force equation f=ma m-=mass, a= acceleration , k=spring constant, x= displacemt due to compression
so, ma=-k x, (mass can not be -ve so remove -ve sign)
m=k x/a= 40*2/3=26.67 kg
