I just realized this and made a fool of myself, really. Way to overthink a problem and not read it properly. I'll go hide in a corner now. Thanks azizlwl!

Homework Statement A swimmer is training in a river. The current flows at 1.33 metres per second and the swimmer's speed is 2.86 metres per second relative to the water. What is the swimmer's speed relative to the shore when swimming upstream? What about downstream? Homework Equations...

You're a life savior. It's this vo sinθ= voy that I wasn't able to get to. I got the answer right. Thank you so much!

Homework Statement A projectile was fired across level ground at an initial angle of 43.00 degrees above the horizontal. During its flight, it reached a maximum height of 2974 metres. What was the initial speed of this projectile? Homework Equations I assume that the correct equation...

Ah, I think I got it! I have to get that dimensions are just that, dimensions. So in truth, a(x - x0) is really just L/T²(L) which is L²/T² I think that's the right conclusion and makes the expression correct. Thanks!

Homework Statement I'm trying to work out if the following is dimensionally correct. I think I'm getting stuck at the (x - x0) Homework Equations In this case v is velocity (L/T), a is acceleration (L/T²), and x represents displacement, which is a length (L) The Attempt at a...
