I'm familiar with the first one being used as d = v0t + ½at^2 and of course i know the second =)

^^ what are x and xo being used to represent?

Yes, I assume "all else" means *everything* is the same... should I just pick a random value and keep it constant?

I still keep getting 50... grr. Okay, so using V2 ------ V1 set equal to Fa ------- 2Fa I've tried cross-multiplying, but I still have too many unknowns to solve for anything. All I know is the change in velocity.

This question is driving me insane... An arrow, starting from rest, leaves the bow with a speed of 25.0 m/s. If the average force exerted on the arrow by the bow were doubled, all else remaining the same, with what speed would the arrow leave the bow? Of course, instinct says 50 m/s, but...

Yep, got it. That was all I needed for it to click in my brain.

Aha! Just what I was looking for, and thanks for not giving me the answer outright, it made it much more rewarding to get the right answer. Thanks again!

Hello, thanks for reading =) Let's just jump into it... At the instant the light turns green, a car accelerates from rest at a rate of 1.8m/s^2. A truck gets to the intersection by the time the light changes [and therefore doesn't have to stop]. The truck is traveling at a constant velocity...

i think I'm going to do something like that, except measure in metres, not litres. it's hard to calculate the flow of water using litres because there's that bit right at the end of the burette that you can't measure. so even though using metres to calculate rate of flow of water is technically...

wouldn't the rate of flow be the same no matter how much water there is? so, the height of the water column doesn't really come into play because you're dividing the amount by time anyway, so it should all be the same rate? or am i totally wrong? my only question about this thing is what...

can anybody help?

Hey there. I'm currently taking grade 11 physics, and as part of our final evaluation, we have to perform an in-class lab. We're not given the procedure, just what we have to determine and a list of apparatus. I have a general idea of what to do, but I'd just like some confirmation if what I'm...
