The person kicks the ball in the image below 20 meters. Suppose the soccer ball in the image is replaced by one that is twice th
e mass of a regular soccer ball. How could the person kick the ball the same distance as the first soccer ball?

Answer:
Height = 53.361 m
Explanation:
There are two balloons being thrown down, one with initial speed (u1) = 0 and the other with initial speed (u2) = 43.12
From the given information we make the following summary
= 0m/s
= t
= 43.12m/s
= (t-2.2)s
The distance by the first balloon is
where
a = 9.8m/s2
Inputting the values
The distance traveled by the second balloon
Inputting the values
simplifying
Substituting D of the first balloon into the D of the second balloon and solving
Now we know the value of t. We input this into the equation of the first balloon the to get height of the apartment
Answer:
C. Impulse = F*t=(m*a)*t= m*(a*t) = m*Dv= D(Momentum) (“D” here’s mean Delta so change in)
Explanation:
In fact, the impulse is equal to the change in momentum of an object.
Impulse is defined as the product between the force (F) and the time (t):
however, the force is defined as the product between mass (m) and acceleration (a):
But the product a (acceleration) times t (time) is equal to the change in velocity of the object:
And this is exactly the definition of change in momentum:
