Problem # 1
Do heavier objects fall more slowly than lighter objects?
Answer
No. If an object is heavier the force of gravity is greater, but since it has greater mass the acceleration is the same, so it moves at the same speed (if we neglect air resistance). If we look at Newton's second law, F = ma. The force of gravity is F = mg, where m is the mass of the object and g is the acceleration due to gravity.
Equating, we have mg = ma. Therefore, a = g.
If there was no air resistance, a feather would fall at the same speed as an apple
Answer:
The kite string is feet long.
Explanation:
Use the Pythagorean Theorem, which is .
Here the question is asking for , which would be the hypotenuse, or the longest side of the triangle.
So the would be , and the would be .
Plug those values into the formula, and that would get .
Now, solve for , which would equal .
That means we would have to solve for .
Square root both sides of the equation, getting .
Solve for , which would get us .
Hence, the answer to this would question would be .

We can get water from the sweat and exhaled breath of the people present in the space station.
<h3>How would you get water?</h3>
We can get water from the sweat and exhaled breath. The water we drink is recycled from the sweat and exhaled breath of the people present in the space station which was collected through condensation on the Space Station's walls.
So we can conclude we can get water from the sweat and exhaled breath of the people present in the space station.

Answer:
F = 25 N
Explanation:
The work done by any force is given as the product of the force and displacement produced by the application of that force. Therefore, the work done by the dog when it pulls the rope attached to the box can be given by the following formula:
where,
W = Work done by the dog while pulling the rope = 250 J
F = Force of pull applied by the dog = ?
d = displacement of the box across the floor = 10 m
Therefore,
<u>F = 25 N</u>
