Step-by-step explanation:
We have,
Mass of ball is 9 kg
Initial speed, u = 5 m/s
Final speed, v = -2 m/s (negative as it bounces off)
(a) The change in velocity of the bowling ball is :
(b) Change of momentum of the ball is :
|p| = 630 kg-m/s
(c) Impulse momentum theorem states that the change in momentum of the ball is equal to the impulse exerted on the ball. So, impulse is 630 kg-m/s.
(d) Impulse is also given by :
Answer:
130 in^2 net area
136 in^2 gross area (counting the 6 in^2 scrap loss for the side cutouts)
Step-by-step explanation:
top=1.5x4=6
middle=1.5x4=6
bottom=3x4=12
sides=(2x3x8)-(2x1.5x2)=42
front & back=2x8x4=64
6+6+12+42+64=130
Answer:
3.25 miles
Step-by-step explanation:
Combine the total laps by doing 6 + 7 to get 13. Then, multiple 13 by 0.25 to get your sum of 3.25 miles.
Answer:
2x+9
Step-by-step explanation:
As you can see, there's a 4x. Now, you want to to to 36x divided by 16x which is 2, 9 to the power of 2 is 81 which is in the polynomial so you'll want to click 2x+9.
Answer:
36/1225 is in the simplest form.
Step-by-step explanation:
The easiest way to simplify a fraction is to look at eachs prime factorization:
36 has the factors:
(1, 2, 3, 4, 9, 12, 18 , 36)
1225 has these factors:
(1, 5, 7, 25, 35, 49, 175, 245, 1225)
Now we look for a common factor greater than 1:
Hmm... there isn't one in these sequences! With that information in our belt, we now know that 36/1225 is in its simplest form.
