The position of particles A and B is described by IA = [2 ti +(t2-1) i and<br />r = [(t + 2)i + (2 t- 5) i), respectively , where t is in seconds. Determine the point<br />where the particles collide and their speeds just before the collision.<br /><br /><br />fast need help.​

answer: 20

step-by-step explanation: subtract the minimum date value from the maximum data value to find the date range. in this casem the date range is 42 - 22 = 20

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
