Question

a graph of position versus time for a certain particle movingalong the x-axis is shown in 2-6 find the average velocity in thetime interval from (a) 0 to 2.00 s (b) 0 to 4.00 s (c) 2.00 sto4.00 s (d) 4.00 s to 7.00 s (e) 0 to 8.00 s   Step 2: Where does the formula come from& how do you know its correct. Step 3: How do the #'s from the chart line up with theformula given. please explain in as much detail as possible,im physic- ally ignorant sometimes. a graph of position versus time for a certain particle movingalong the x-axis is shown in 2-6 find the average velocity in thetime interval from (a) 0 to 2.00 s (b) 0 to 4.00 s (c) 2.00 sto4.00 s (d) 4.00 s to 7.00 s (e) 0 to 8.00 s   Step 2: Where does the formula come from& how do you know its correct.

Explanation / Answer

   the formula is    velocity = distance / time so that (a)    v = x / t         = 10.0 m / 2.00 s       = ....... m / s (b)    v = x / t         = 5.0 m / 4.00 s       = ....... m / s (c)    v = x / t         = (5.0 m - 10.0m) / (4.00 s - 2.00 s)       = ....... m / s (d)    v = x / t         = (- 5.00 m - 5.00 m)/ (7.00 s - 4.00 s)       = ....... m / s (e)     (a)    v = x / t         = (x2 -x1) / (t2 - t1)       = ....... m / s (b)    v = x / t         = 5.0 m / 4.00 s       = ....... m / s (c)    v = x / t         = (5.0 m - 10.0m) / (4.00 s - 2.00 s)       = ....... m / s (d)    v = x / t         = (- 5.00 m - 5.00 m)/ (7.00 s - 4.00 s)       = ....... m / s (e)     (a)    v = x / t         = (x2 -x1) / (t2 - t1)       = ....... m / s (c)    v = x / t         = (5.0 m - 10.0m) / (4.00 s - 2.00 s)       = ....... m / s (d)    v = x / t         = (- 5.00 m - 5.00 m)/ (7.00 s - 4.00 s)       = ....... m / s (e)     (a)    v = x / t         = (x2 -x1) / (t2 - t1)       = ....... m / s (d)    v = x / t         = (- 5.00 m - 5.00 m)/ (7.00 s - 4.00 s)       = ....... m / s (e)     (a)    v = x / t         = (x2 -x1) / (t2 - t1)       = ....... m / s (a)    v = x / t         = (x2 -x1) / (t2 - t1)       = ....... m / s
