Answer:
Knowing we only have one load applied in just one direction we have to use the Hooke's law for one dimension
ex = бx/E
бx = Fx/A = Fx/π
Using both equation and solving for the modulus of elasticity E
E = бx/ex = Fx / πex
E =
Apply the Hooke's law for either y or z direction (circle will change in every direction) we can find the change in radius
ey = (бy - v (бx + бz)) =
бx
= =
Finally
ey = Δr / r
Δr = ey * r = 10 *
Δd = 2Δr =

Answer:
2.72 m/s
Explanation:
In 3 meters a person running 0.5 m/s accelerates 1.2 m/s².
It means,
Distance, s = 3 m
Initial velocity, u = 0.5 m/s
Acceleration, a = 1.2 m/s²
We need to find the final velocity of the person. Using equation of motion to find it as follows :
So, the final velocity of the person is 2.72 m/s.
