Mr. Seto, I have to confess that I'm not sure things are going to work
out for you to be a scientist. Every scientist knows how to do
calculations of all kinds.
For example lets suppose that I were to toss a ball directly up in the
air at say 60 feet per second. When I do this I want to be able to
predict how long it will be up in the air. I want to make this
prediction to see how well some equations work that I've been taught.
When I get that number I can compare that to how long someone else
measures it to be in the air with a stopwatch. If the prediction is
right then I know the equation is right.
The equation I've been taught is
y = v0 * t - (1/2) * g * t^2.
Now I know v0 because it is 60 ft per second.
I know g because it is 32 ft per second squared.
I know y because it lands on the ground and so is -3 ft below where I
threw it from.
Now I should be able to predict the time t because it is the only
variable I don't know in the equation. But I can use the equation to
calculate it. And you can use the equation to calculate it too because
you want to be known as a scientist and so you must be able to do
calculations and this is a very simple calculation.
Let's say my answer that I calculated is 4.3 seconds. Is the answer
you calculated the same or different than this answer, Mr. Seto?
Since you want to be known as a scientist, Mr. Seto, please do this
calculation to show that you are a scientist.
