(3.6 newton-second) / (600 newton) = 0.006 second
Answer:
Explanation:
First Law of Motion: Law of Inertia.
An object in motion stays in motion unless an outside force is applied to the object to make it stop, and an object at rest will stay at rest unless an outside force is applied to make the object move.
Second Law of Motion: Law of Acceleration.
It explains the equation with force. Force is equal to mass times its acceleration. It also explains how mass can affect acceleration. They are inversely proportional. Mass can decrease acceleration.
Third Law of Motion: Law of Action-Reaction.
For every action that occurs on an object, an opposite reaction occurs. This explains how forces act in pairs, there is an action force and a reaction force.
The minimum work needed to pus the cart up the inclined plane is 960000 J.
<h3>What is work done on a inclined plane?</h3>
The work done on a inclined plane is given below as:
- Work done = force * distance
Distance = 700 m
The force on an inclined plane, F = mgsinθ
where;
m is mass in kg
g = 9.81 m/s²
θ = 8.5°
Work done = 950 * 9.81 * sin 8.5 * 700
Work done = 960000 J
Therefore, minimum work needed is 960000 J.
In conclusion, the work done is a product of force and distance.

Answer:
In a truss bridge, two long - usually straight members known as chords - form the top and bottom; they are connected by a web of vertical posts and diagonals. The bridge is supported at the ends by abutments and sometimes in the middle by piers.
