The general effort force equation for block and tackle to raise or pull a load can be expressed as
<span><span>S=<span>F/<span>μn</span></span></span>
</span>
where
<span>S
</span> is the effort force,
<span>F
</span> is the load force (often the weight of the object to be moved),
<span>μ
</span> is the mechanical efficiency of the system (1 in an ideal, massless, frictionless system of pulleys), and
<span>n
</span> is the number of ropes between the sets of pulleys.
Answer:
gravity
Explanation:
Gravity pulls the planets toward the Sun. Gravity pulls the moon toward Earth. Gravity pulls us toward the Earth. Gravity is a force. Inertia.
To find the acceleration of the car, we can use the equation acelleration=final velocity-initial velocity/elapsed time. Since we know the initial velocity is zero from the start, than we can calculate it as final velocity/elapsed time. If we divide 36 by 10, we get 3.6. Your acceleration is 3.6 km/h.

The distance and the direction is 3 blocks East and then 3 blocks North.
<h3>What is distance to be travelled to go from point A to point B?</h3>
Distance is a measure of the space between two points.
Distance follows the path of travel of all object adding up all the spaces between the objects.
Displacement on the other hand is the distance travelled in a specific direction.
Displacement measures the shortest distance between two points in a specified direction.
The displacement of point from A to B is given as 3.606 blocks in a direction 33.69 ∘ north of east.
To determine the distance and direction of travel, the best possible route of travel is moving 3 blocks to the East and then 3 blocks to the North.
In conclusion, the distance travelled follows all the path of travel to get from one point to another.

Answer:
<em>Andrew's dog's speed was 1.89 m/s</em>
Explanation:
<u>Motion at Constant Speed</u>
An object is said to travel at constant speed if the ratio of the distance traveled by the time taken is constant.
This can be written as the formula below:
Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
Andrew's dog run a distance of d=17 meters in a time of t=9 seconds, thus its speed was;
v = 1.89 m/s
Andrew's dog's speed was 1.89 m/s
