Answer: I didn't see a difference because the large ball's vertical displacement and velocity are the same as the small one's.
Explanation:
To find out scientific notation, you want to make sure that number is less than 10. So do 5.000000, you don't rally need the zeros but I just want to make my point. So use 10^x meaning ten the whatever power adds zeros like 5.000000x10^6 meaning it is increasing it by six zeros moving it out of the decimals and letting become 5,000,000.
Speed = distance / time
If you input your numbers into this equation you will be able to find the cyclists average speed
