the coefficient of static friction between a 40 kg picnic table and the ground below is .43. what is the greatest horizontal for
2 answers:
Answer:
The greatest horizontal force that can be exerted without moving the table is 168.56N.
Explanation:
The maximum friction force is determined from the coefficient of static friction as follows:
where the the normal force is exerted by the ground as a reaction to the weight of the table, and has same magnitude as but opposite direction to the gravitational force on the table:
This is the <em>maximum</em> static force, so the friction force will be matching and opposing any horizontal force up to 168.56N.

The acceleration of this car is equal to 5 .
<u>Given the following data:</u>
- Initial velocity = 0 m/s (assuming it's starting from rest).
- Final velocity = 10 m/s.
- Time = 2 seconds.
To determine the acceleration of this car:
<h3>How to calculate acceleration.</h3>In Science, the acceleration of an object is calculated by subtracting the initial velocity from its final velocity and dividing by the time.
Mathematically, acceleration is given by this formula:
<u>Where:</u>
- V is the final velocity.
- U is the initial velocity.
- is the time measured in seconds.
Substituting the given parameters into the formula, we have;
Acceleration, a = 5

Answer:
12 units
Explanation:
This problem can be solved if we take into account the equation for a sphere
where we took that the radius is 13 units. If we take z=5 and we replace this value in the equation of the sphere we have
where we have taken x2 +y2 because if the equation of a circunference.
In this case the intersection is made when we take z=5, for this value the sphere and the plane coincides in values.
Hence, the radius is 12 units
