1A.7 Resolving vectors

Question 1

what is resolving vectors

Answer 1

the determination of a pair of vectors are at right angles to each other that sums to give the single vector they were resolved from

Question 2

how can we resolve vectors using calculations

Answer 2

1. so we need the size and direction of the original vector along with the given angle, after that, we need to draw a horizontal line and a vertical line along the original vectors then figure out the horizontal and vertical components by trig
2. or if given the velocity of an object draw the direction of the object and its speed then continue similarly to the first way

Question 3

what is the right angle trig rule
