They both scored a total of 144 points. A had 2+ the amount of points of B.
144/2 = 72.
73 to 71 will be the score.
A scored 73 points.
Doesn’t make sense to me srry
Answer:
63 Inches.
Step-by-step explanation:
2 yards - 9 inches is equal to 1.75 yards and when converted to inches, equals 63 inches.
The magnitude of the final velocity of the cue ball is (B) 0.56m/s.
<h3>
What is Velocity</h3>
- The definition of velocity is a vector measurement of the rate and direction of motion.
- It is a moving body's speed and direction of motion.
How to calculate the magnitude of the final velocity?
The magnitude of the final velocity can be calculated by following the steps:
- The mass of the cue ball given is 0.4kg.
- The velocity of the cue ball given is +0.80m/s.
- The velocity of the striped ball before the collision is +0.38 m/s.
- The velocity of the striped ball after collision is +0.62m/s.
- We need to find the magnitude of the final velocity of the cue ball.
Assuming all pool balls have the same mass: 0.4kg
Let the final velocity of the cue ball be x.
Now, To find the final velocity:
- Mass of the cue ball × initial velocity of cue ball + Mass of striped ball + initial velocity of striped ball = mass of cue ball × final velocity + mass of striped ball × final velocity of the striped ball
- (0.40)×(0.80)+(0.4)(0.38) = (0.4)(x)+(0.4)(0.62)
- 0.32+0.152=0.4x+0.248
- 0.472=0.4x+0.248
- 0.472-0.248= 0.4x
- 0.224/0.4 =x
- x = 0.56m/s
Therefore, the magnitude of the final velocity of the cue ball is (B) 0.56m/s.

The correct question is given below:
In a game of pool, a 0.4 kg cue ball is traveling at +0.80 m/s when it hits a slower striped ball moving at +0.38 m/s. After the collision, the striped ball moves off at +0.62 m/s. What is the magnitude of the final velocity of the cue ball? Assume all pool balls have the same mass.
A. 0.20 m/s
B. 0.56 m/s
C. 1.0 m/s
D. 1.8 m/s
You have to write a word problem where (a * x) + b is greater than c. One situation could start with (a * x) where a is 2, and x is another number, lets say 5. You have to multiply those and then add b, which we could say is 2, for the sake of it. Then all of those together has to be more than c, which could be 9 for this problem. Then you have to show your work and graph on a number line and all that stuff, and explain what your solution means in the context of the problem. That could be what the numbers mean in relation to others, or what a, x, b, and c are.
