indentation d of the ball into the clay.
(m/s) (m)
1.30 0.02
5.00 0.30
9.13 1.00
b. If the ball is going 20 meters per second, how far into the
clay should it go?
10.00 1.20
12.91
15.00
2.00
2.70
20.00
7.50
C. How fast was the ball going to make a 7.5 meter impact

The inequality shows that there x makes up the 10-point scores, and y makes up the 20-point scores. To know which of the choices cannot be true, we can analyze each choice:

A. It is not possible to have a fraction of a score, so this must be true.
B. They must be positive numbers. 
C. Similar to B, they must be positive numbers.
D. Even with a value less than 5, the inequality can be met. 

Therefore, the correct answer is D.
