Resultant TIP-TO-TAIL + 8 km + ? m/s We’ll figure out how to get the magnitude of a vector like this one later on in the chapter
Tip-to-Tail
100 km scalar Pythagorean Theorem 72.1 km Tail-Tail 60 km Greek 40 km SOH CAH TOA
CAUTION! radian 72.1 km [ N 56.3o E]
Tip-to-Tail
71.6 degrees 6.32 m/s RESULTANT COMPONENTS zero
= B + (- A) B – A = B + D + D B + 2D
