Answer:
When mass increases, kinetic energy also increases. Changing mass doesn’t affect his speed on a given ramp.
Explanation:
Answer:
a) -31.36 m/s
b) 50.176 m
Explanation:
<h2>a) Velocity of the bag</h2>
This is a problem of motion in one direction (specifically vertical motion), and the equation that best fulfills this approach is:
(1)
Where:
is the final velocity of the supply bag
is the initial velocity of the supply bag (we know it is zero because we are told <u>it was "dropped", this means it goes to ground in free fall</u>)
is the acceleration due gravity (the negtive sign indicates the gravity is downwards, in the direction of the center of the Earth)
is the time
Knowing this, let's solve (1):
(2)
Hence:
Note the negative sign is because the direction of the bag is downwards as well.
<h2>b) Final height of the bag</h2>
In this case we will use the following equation:
(3)
Where:
is the distance the bag has fallen
remembering <u>the bag was dropped</u>
is the acceleration due gravity (downwards)
is the time
Then:
(3)
(4)
Finally:
A lewis electron dot diagram (or electron dot diagram) is a representation of the valence electrons of an atom that uses dots around the symbol of the element. the number of dots equals the number of valence electrons in the atom.
