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
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...
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...
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 =...
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.
