I do a yoga mat that could be different to your answer
Answer:
when it hit the moving bat
Explanation:
force equals mass times acceleration which means the moving bat will add more force to the ball.
Answer:
At low pressure- 
At high pressure- 
Explanation:
Initial speed, 
Final speed, 
Net horizontal force due to rolling friction 
mg where m is mass, g is acceleration due to gravity, 
is coefficient of rolling friction
From kinematic relation, 
For each tire,
Making the subject
Under low pressure of 40 Psi, d=18 m
Therefore,
At a pressure of 105 Psi, d=93.7
Therefore,
its a solid from the pressure they put on a tennis ball would make it full of moving at fast speed matter bites compacted together but still moving.
You would have to place your sensor above earth's atmosphere because it blocks out nearly all x-rays. this is why we have the Chandra observatory
hope this helps
