yes i understand now thank you so much ;]

should it be 9.8 x 2 = 19.6m/s at 2 second?

how will i know the velocity change every second when i can't solve that because it doesn't tell time. It tells me to answer with words and that its not a math problem.

vf = vo + at ? and the teacher said for free fall it's vf = gt

that no matter what time or how long it stays at g = 9.8 m/s

Let's say a rock had a speedometer on it so that you could measure how fast it was going at any moment. By how much would the speed reading on the speedometer increase with each second that it fell? what is your answer to this question? can you explain? i also learned today that g = 9.8...

because it's like this d= 11.18^2 / 2 * -3 = 125 / -6 = -20.83 how can it not be negative?

mgb_phys i got -20.83. is that right?

d = 125 / 2 * -3 d = 125 / -6 d = -20.83 is this right?

at the end i got d = -9 / 2a what do i do after this? -9a / 2a = -9 / 2 d = -4.5 is that right?

how is vf 0 when it only tells me meters per second is 11.18 and acceleration -3m/s?

nvm this is what i got... vf^2 = 2ad 127/2a = d after that? 127a/2a = 127 / 2 = 63.5?

using the 3rd formula i got.. vf^2 = 125 + 2ad /2a both side vf^2 / 2a = d and then what else do i do? and is this right?

the 11.18 is the vi. How can i do this problem can you show me step to step? i have like 10 of these and hope to see how to do this one first.

Acceleration = -3m/s^2 Meters per second = 11.18 if i were to find the stopping distance what formula should i use? Vo + at = Vf d = Vo x t + 1/2 x at^2 Vf^2 = Vo^2 + 2ad
