U guys are right Vectors don"t suck. I think I was just frustrated with the rest of my work. I am taking physics and that was a physics problem. Any ways I got all the answers right on CAPA, so everything rocks! :-p Time to :zzz: :zzz:

A particle moves in the x-y plane with constant acceleration. At time t = 0 s, the position vector for the particle is d = 2.2 m x + 8.2 m y. The acceleration is given by the vector a = 4.5 m/s2 x + 2.2 m/s2 y. The velocity vector at time t = 0 s is v = 3.3 m/s x - 4.3 m/s y. Find the magnitude...

?? OK, V1= of 3.0 m/s and is directed along the +x-axis. V2=2.0 m/s. So V3 = V1+V2. Right. I was never really shown how to add vectors. Thanks.

Yes! Thanks needhelpperson that worked and really helped. I will remember that for next time.

Ok OK, I'll put it in my Calc and see what I get. Thanks PRodQuanta and needhelpperson.

How do you add two vector magnitudes and find x components?

An object is moving in a straight line with a constant acceleration. Its position is measured at three different times, as shown in the table below. Time (s) | Position, (m) 56.40 | 9.700 58.20 | 19.042 60.00 | 38.428 Calculate the magnitude of the acceleration at t=58.20 s I am not...

Thanks Thanks to everyone in here who helped. I got the answer after beating myself with a hammer and realizing how easy it was. :smile:

A small steel ball bearing with a mass of 11.0 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.37 m. Calculate the horizontal distance the ball would travel if the same spring were aimed 30.0 deg from the horizontal...
