1. ### Simple Vector Problem - Finding the x-component

I thought of that after I posted it and came up with -1, 0 as the x,y components [using cos180 and sign 180) which was still wrong. it's late so I wasn't thinking clearly :P
2. ### Simple Vector Problem - Finding the x-component

Homework Statement Find x- and y-components of the following vectors v = 7.0 cm/s, negative x-direction Homework Equations Vx = |V|Cos(Theta) Vy = |v|Sin(Theta) The Attempt at a Solution I'm a bit stuck here. I slotted in 7cm/s for |v| but how do I find the components if I'm not given an...
3. ### Simple Vector Problem - Finding the x-component

Oops sorry, nevermind, I realised that in Step 2 I should have divided by Sin(-45) apologies!
4. ### Simple Vector Problem - Finding the x-component

Homework Statement A velocity vector 45 below the positive x-axis has a y-component of - 29 . What is the value of its x-component? Homework Equations Vx = |V|Cos(Theta) Vy = |v|Sin(Theta) The Attempt at a Solution Theta = -45 degrees y-component: -29 = xSin(-45) .... where x...
5. ### [Collision with 2 Clay Balls] [Inelastic Collisions] [Help Finding Theta]

Nevermind, I worked it out in the end. For anyone on the same problem, just get the momenta of the two balls, and then divide the momenta by the final mass (0.09kg) to get the velocities in the X and Y directions. Then simply use the baldy Greek's theorem (Pythagoras). x momentum =...
6. ### [Collision with 2 Clay Balls] [Inelastic Collisions] [Help Finding Theta]

Here's my problem guys, I've been trying to puzzle this out for a while. Would really appreciate any help at all, thanks! Homework Statement A 50.0 g ball of clay traveling east at 5.50 m/s collides and sticks together with a 40.0 g ball of clay traveling north at 6.00 m/s. What is the...
