Question

Need help on a math project involving vertical motion and quadratic equations such as h(t)=-16t+v0(t)+s

Answer 1

alright. but i dont see a quadratic term in there.
did you typo where you have time +s? is it time^2?

Answer 2

Oh, yes, I did miss a ^2, my bad!
It should be -16x^2.

Our project is basically us dropping a tennis ball off the second story of a building.
Also, we are given the time (t) as 0.85 seconds, where the ball took .85 seconds to reach the ground. We're supposed to figure out how tall the building was/initial height and then figure out the initial velocity.

Answer 3

well. if your dropping the ball. what is the velocity when it is in your hand

Answer 4

Oh, you're right. The initial velocity should be zero. That was probably why I was so confused when it asked me to solve.

Answer 5

what does the s represent at the end of the function?

Answer 6

The s represents initial height

Answer 7

well. you can plug your time in for t. then solve for s. but you will still have a variable y in there

Answer 8

Okay, I think I understand the equation now. Thank you for your help!

Answer 9

yep
