Homework Statement
For V(t) = (1+t)i + (t^2-2t)j find:
1. velocity
2.Acceleration
3. speed/length
4. Unit Tangent
5. tangential component
6. normal component at t=2
Homework Equations
The Attempt at a Solution
1. v'(t) = <1,2t-2> = <1, 2(t-1)>
2. a(t) = <0,2>
3. length = Square root of (1+4(t-1)^2)
4. Unit Tangent = <1,2(t-1)> / square root (1+4(t-1)^2)
from here I'm stuck trying to find the tangential component and normal component. [/B]
