Y I believe equals 8 I hope I helped
Brainliest would be nice:) :)
Answer: 3.
Step-by-step explanation:
The impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.
<h3>What is Impulse?</h3>
An impulse is simply a concept that involves the change in the momentum of an object when force is introduced for a period of time.
It is expressed as;
ΔP or Change in Momentum = F × t
Where F is force applied and t is the elapsed time.
Given that;
- Mass of baseball m = 0.25kg
- Time of contact t = 0.0075s
- Force exerted F = 18500N = 18500kgm/s²
We substitute our given values into the expression above to determine the impulse.
ΔP = F × t
ΔP = 18500kgm/s² × 0.0075s
ΔP = 18500kgm/s² × 0.0075s
ΔP = 138.75kgm/s = 140kgm/s
Therefore, the impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.

5x - 3y + 1 = 16 ⇒ 10x - 6y + 2 = 16
2x + 5y + 0 = -6 ⇒ <u>10x + 25y + 0 = -6</u>
31y + 2 = 10
<u> -2 -2</u>
<u>31y</u> = <u>8</u>
31 31
y = 8/31
5x - 3(8/31) + 1 = 16
5x - 24/31 + 1 = 16
5x + 7/31 = 16
<u> -7/31 -7/31</u>
<u>5x</u> = <u>10 24/31</u>
5 5
x = 2 24/155
(x, y) = (2 24/155, 8/31)
4 thousands = 4000
7 hundreds = 700
16 tens = 160
9 ones = 9
Then you add them all together:
4000 + 700 + 160 + 9
Your answer is 4869.
