Distance Formula and Pythagorean Theorem Example: The distance between (3, 4) and (x, 7) is 5 units. Find x. Using the distance formula: (3 —x)2 + (4—7) x) 3 Solving Graphically (Pythagorean Theorem) Example: b b 3 -5 4 or -4 The length of segment AB is 20. If the coordinate of Ais (5, 1), and the coordinate of B is (-6, y), what is b?
2-1 Position, Displacement, and Distance In describing an object’s motion, we should first talk about position – where is the object? A position is a vector because it has both a magnitude and a direction: it is some distance from a
Justification: In order to determine if Jordan escapes or is caught we must check if the distance between Jordan and the Lion reaches zero at a time before or after Jordan reaches the Land Rover. The first step in solving this problem is breaking it into two segments.
“linear” quantities (distance s, speed v, tangential acceleration at) are related to the angular quantities (angle θ, angular speed ω, angular acceleration α) by a factor of r : s = r θ, v = r ω, a t = r α.
