How much work was done by a hot air balloon to lift up a 100 Newton to a height of 300 meters?
Monica [59]

So, the work was done by that hot air-balloon is <u>30,000 J or 30 kJ</u>.

<h3>Introduction</h3>

Hi ! In this question, I will help you. <u>Work is the amount of force exerted to cause an object to move a certain distance from its starting point</u>. In physics, the amount of work will be proportional to the increase in force and increase in displacement. Amount of work can be calculated by this equation :

\boxed{\sf{\bold{W = F \times s}}}

With the following condition :

  • W = work (J)
  • F = force (N)
  • s = shift or displacement (m)

Now, the s (displacement) can be written as ∆h (altitude change) because the object move to vertical line. The formula can also be changed to:

\boxed{\sf{\bold{W = F \times \Delta h}}}

With the following condition :

  • W = work (J)
  • F = force (N)
  • \sf{\Delta h} = change of altitude (m)

If an object has mass, then the object will also be affected by gravity. Always remember that F = m × g. So that :

\sf{W = F \times \Delta h}

\boxed{\sf{\bold{W = m \times g \times \Delta h}}}

With the following condition :

  • W = work (J)
  • m = mass of the object (kg)
  • g = acceleration of the gravity (m/s²)
  • \sf{\Delta h} = change of altitude (m)

<h3>Problem Solving</h3>

We know that :

  • F = force = 100 N
  • \sf{\Delta h} = change of altitude 300 m

What was asked :

  • W = work = ... J

Step by step :

\sf{W = F \times \Delta h}

\sf{W = 100 \times 300}

\boxed{\sf{W = 30,000 \: J = 30 \: kJ}}

<h3>Conclusion</h3>

So, the work was done by that hot air-balloon is 30,000 J or 30 kJ.

katrin2010 [14]

Explanation:

a. Average speed = distance / time

= 100 m / 70 s

= 1.43 m/s

b. Average displacement = displacement / time

= 0 m / 70 s

= 0 m/s

Distance is the length of the path traveled.  Displacement is the difference between the final position and initial position.

Two trains leave a train station traveling in the same direction. They leave at the same time. Train A moves at 41.1 mph and Tra
hammer [34]

The time taken for Train A to be 39.1 miles ahead of Train B is 2.7 hours

<h3>How to determine the relative speed</h3>
  • Speed of Train A = 41.1 mph
  • Speed of Train B = 26.5 mph
  • Relative speed =?

Relative speed = 41.1 - 26.5

Relative speed = 14.6 mph

<h3>How to determine the time to be 39.1 miles apart</h3>
  • Relative speed = 14.6 mph
  • Distance = 39.1 miles
  • Time =?

Relative speed = distance / time

14.6 = 39.1 / time

Cross multiply

14.6 × time = 39.1

Divide both side by 14.6

Time = 39.1 / 14.6

Time = 2.7 hours

Thus, it will take train A 2.7 hours to be 39.1 miles ahead of Train B
