Sagot :
Answer:
only E is true
Explanation:
A) to find out if it would fall 4x as fast by 2x the time we can look at the formula for free fall:
for free fall the Y = [tex]\frac{1}{2}[/tex]g[tex]t^{2}[/tex] where Y is the distance fallen, g is gravity and t is time
so since the rate at which an object falls is the same (gravity stays the same) it will not fall faster with any alteration
B) An object would fall half the distance if you double the time
here we may need to check with an example:
lets say we fall for 2 seconds in the first and 4 in the second:
Y= 1/2 (9.8) (2)^2 gives 19.6m fallen
Y= 1/2 (9.8) (4)^2 gives 78.4m fallen
from this we can see that doubling the time does not half the distance
C) all objects fall at the same rate no matter their mass so this statement is false
D) from the example above we see again that doubling time does not double the distance
E) this statement is true
Option e is correct. So that a 2 kg object falls as fast as a 1 kg object. Height attained depends upon the time factor.
What is height?
The vertical distance between the object's top and bottom is defined as height. It is measured in centimeters, inches, meters, and other units.
The height attained during free fall ;
[tex]\rm H = ut + \frac{1}{2}gt^2 \\\\ u = 0 \\\\ H=\frac{1}{2}gt^2[/tex]
The height attained during free fall is independent of the mass. Due to that, a 2 kg object falls as fast as a 1 kg object.
Hence,option e is correct.
