Remark

The object is moving at a constant acceleration. The acceleration is not given, but it does permit you to use d = (vi + vt)*t/2

Givens

vi = 1 (This is important.

d = 21 m (read from the graph) You have to go up just a little bit from 20

vf = ???

t = 10 s

Solve

d = (vf + vi)*t/2

21 = (vf + 1) * 10/2 Multiply by 2

42 = (vf + 1) * 10 Divide by 10

4.2 = vf + 1 Subtract 1

4.2 - 1 = vf

vf = 3.2 Answer

The graph seems to show the position at t=10 s to be x=21 m. Thus, the position has changed at the average rate of

... (21-1) m/(10 s) = 2.0 m/s

The average is half the sum of initial and final velocities, so we have

... 2.0 m/s = (1/2)(1.0 m/s + vf)

... 4.0 m/s - 1.0 m/s = vf = 3.0 m/s

The final velocity is 3.0 m/s.

Answer:

The answer to your question is:

12) C

13) AT = 29

Step-by-step explanation:

12)

Data

A (6, -3)

B (-6, 19)

midx = (x1 + x2) / 2                            midy = (y1 ´y2) / 2

midx = ( 6 - 6) / 2                               midy = (-3 + 19) / 2

midx = 0 / 2                                      midy = 16 / 2

midx = 0                                            midy = 8

               mid point = (0, 8)

13)

As A is the midpoint of CT then CA = AT

                                  2x - 19 = x + 5

                                  2x - x = 19 + 5

                                  x = 24

                AT = 24 + 5

                AT = 29

A student walked 100 meters north, then 100 meters west. how many more meters did the student walk compared to their total displ
seraphim [82]

Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.

If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).

Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.

c^2 = a^2 + b^2

where c is the total displacement from the starting point to the end point

a is the distance he walks up north

b is the distance he walks to the west

c^2 = 100^2 + 100^2

c^2 = 10,000 + 10,000

c^2 = 20,000

c = 141.42 meters

Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.

100 meters + 100 meters - 141.42 meters = 53.58 meters
