A 50.0-kg box rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.300 and the
2 answers:
Answer:
<em>The frictional force is 140 N</em>
Explanation:
The static frictional force can be calculated with the expression below;
F = μmg
where F is the static frictional force
μ is the coefficient of static friction = 0.300
m is the mass of the body = 50 kg
g is the acceleration due to gravity = 9.8 m/
Substituting into the equation above;
F = 0.300 x 50 kg x 9.8 m/
F = 147 N
With a static force of 147 N which is greater than the applied force 140 N, the box will not move.
The frictional force on the box if a horizontal force of 140 N will be the same as the horizontal force. Therefore the frictional force would be 140.

The braking distance is the distance traveled by a car experiencing a braking force until it comes to rest.
Our initial energy is solely kinetic:
And, since the car goes to rest, it is no longer in motion. It will have no kinetic energy.
Therefore, there was work done by the braking force.
Recall the definition of work:
Or in this case, since the displacement and breaking force are antiparallel:
This is equivalent to the dissipation of kinetic energy:
Now, to visualize this, let's rearrange the equation to solve for displacement.
<u>There is a direct, SQUARE relationship between necessary braking distance speed. </u>
If the speed was reduced by 10.3 percent, its new speed is only 89.7% percent of the original, so:
The reduction by a percentage is:
