Tracks :

  2. MP3LogoParty People (the Kgbs remix)



Physics problems please help?

1. If a=12i^ - 16j^ and b=-24i^ + 10j^, what is the magnitude of the vector c=2a - b
i^=i hat(the "^" goes over the i)

2.If c=[2.5cm, 80*] i.e. the magnitude and direction of c are 2.5cm and 80*, d=[3.5cm, 120*] and e=d - 2c, then what is the dirction of e(to the nearest degree)

3. Two vectors, a=5i^+6j^+7k and b=3i^-8j^+2k^, are drawn starting at the same point. What is the angle between them?
