The only reason why i am concerned is that it just does not make sense that v2 is positive because it is flying [down] compared to v1 which is flying up. I understand that when i measure v2 it is accelerating down in the negative direction which makes it positive. Therefore my answer has to be...
Sorry to post again but i am confused about something else as well.
To get the second velocity i can also use v2 = v1 + a*t
If i do it this way i get -27 [up] instead of 27 [up] as with previous equation.
First, i am confused as to why i get different results? I understand that the question...
I have to square root 27.4 again? I mean i got the answer by square rooting, why do i have to do it again? I have a feeling i started overcomplicating things again...
So in this case it has to be negative right?
Did i just not get the negative because for displacement i used -38m, instead of just 38 which should be used this time around?
Thanks for the warm welcome :)
Homework Statement
Marian, who is standing on her balcony, is surprised by a pigeon and throws a flowerpot up in the air at 2.1 m/s. It takes 3.0 s for the flowerpot to smash to the ground. The flowerpot experiences acceleration due to gravity of 9.81m/s2 [down].
a) How high is Marian's...
I was actually just thinking about this, it looked somewhat odd to me!
I got the idea in an example that i saw earlier. It was a similar problem but acceleration was found first. It went something like this "Kareem was driving his truck at 94 km/h [west]. He starts to apply brakes when he...
Homework Statement
Andrew is driving his van to deliver groceries in Elmvale. As he travels along Hwy 92, a fox stops on the road. Andrew is traveling at 75 km/h [North] and is 42 m away from the fox when he applies his brakes. It takes him 3.4 s to stop.
a) How far did Andrew travel...
