Answer: 10.36m/s
How? Just divide 200m by 19.3 and you will get how fast he ran per m/s
The answer is a dense substance that is hard and incompressible.
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
Hoped I helped!
By looking at the acceleration of the object.
In fact, Netwon's second law states that the resultant of the forces acting on an object is equal to the product between the mass m of the object and its acceleration:

So, when static friction is acting on the object, if the object is still not moving we know that all the forces are balanced: in fact, since the object is stationary, its acceleration is zero, and so the resultant of the forces (left term in the formula) must be zero as well (i.e. the forces are balanced).
Answer:
The value is 
Explanation:
From the question we are told that
The initial speed is
at a distance of 
The final speed is
at a distance of 
Generally from the kinematic equation we have that

=> 
=> 
=> 
The negative sign shows that it is decelerating
