Explanation:
Strain energy is defined as the energy stored in a body due to deformation. The strain energy per unit volume is known as strain energy density and the area under the stress-strain curve towards the point of deformation. When the applied force is released, the whole system returns to its original shape.
Answer:
<h3>The answer is 9 kg</h3>
Explanation:
To find the mass given the force and acceleration we use the formula

where
f is the force
a is the acceleration
We have
f = 18 N
a = 2 m/s²
We have

We have the final answer as
<h3>9 kg</h3>
Hope this helps you
Answer and Explanation:
Data provided in the question
Carbon mass = m
Initial speed = v_i
Coefficient = μk
Based on the above information, the expressions are as follows
a. By using the energy considerations the expression for the carton moving distance is
As we know that

where,





b. The initial speed of the carton if the factor of 3 risen, so the expression is




The particle in the air match the mass with the particles around the balloon stoping it from floating any higher
Twice the distance to double an impact
