If you're moving, then you have kinetic energy.
If you're not at the bottom yet, then you still have
some potential energy left.
A higher temperature, stiffer materials, and less dense materials increase the speed of sound.
Answer:
Explanation:
Give that,
Spring constant (k)=40N/m
Force applied =75N
Since the force is applied to the right, we don't know if it is compressing or stretching the spring
So let assume it compress
Using hooke's law
F=-ke
e=-F/k
Then, e=-75/40
e=-1.875m
The deformation is 1.875m.
Let assume it stretch
Using hooke's law
-F=-ke
e=F/k
Then, e=75/40
e=1.875m
The elongation is 1.875m
normal force because it is perpendicular to the surface
