Below is an attachment containing the solution.
Answer:
the reason for the acceleration month that the coefficient of kinetic friction is less than the coefficient of satic frictionExplanation:
This exercise uses Newton's second law with the condition that the acceleration is zero, by the time the body begins to slide. At this point the balance of forces is
fr- w || = 0
The expression for friction force is that it is proportional to the coefficient of friction by normal.
fr = μ N
When the system is immobile, the coefficient of friction is called static coefficient and has a value, this is due to the union between the surface, when the movement begins some joints are broken giving rise to coefficient of kinetic friction less than static.
In consequence a lower friction force, which is why the system comes out of balance and begins to accelerate.
μ kinetic <μ static
In all this movement the normal with changed that the angle of the table remains fixed.
Consequently, the reason for the acceleration month that the coefficient of kinetic friction is less than the coefficient of satic friction
Not sure if this is right but I think it’s TRUE sorry if it’s wrong....
The definition for model system is for particular species of animal that has been developed over many years to be experimentally powerful to answer particular questions
Answer:
B) 1/5 ba^2 T^5
Explanation:
The dissipated energy is given by the work done over the object by the force F=-bv. The work is given by the following formula:
you derivative the function f(x) and replace v by the derivative dx/dt you obtain:
hence, the dissipated energy is 1/5 ba^2 T^5
