Question

please help i'll medal + fan :)
The graph shows the height of a hiker above sea level. The hiker walks at a constant speed for the entire trip. What are the variables? Describe how the variables are related at various points on the graph.

Answer 1

A. The variables are height and time. For the first part of the graph, the height is increasing slowly, which means the hiker is climbing a steep incline. Flat parts of the graph show where the elevation does not change, which means the hiker stopped to rest. The steep part at the end of the graph shows that the hiker is descending a gentle slope.

B. The variables are height and time. For the first part of the graph, the height is increasing slowly, which means the hiker is walking up a gentle slope. Flat parts of the graph show where the elevation does not change, which means the trail is flat here. The steep part at the end of the graph shows that the hiker is descending a steep incline.

C. The variables are height and time. For the first part of the graph, the height is increasing slowly, which means the hiker is climbing a steep incline. Flat parts of the graph show where the elevation does not change, which means the trail is flat here. The steep part at the end of the graph shows that the hiker is descending a steep incline.

D. All of the above

Answer 3

@ganeshie8 @SolomonZelman

Answer 4

at constant speed ---> acceleration is zero.
Vx and Vy V=sqrt(Vx^2+Vy^2)

Answer 5

im confused @AJ01

Answer 6

ik acceleration will be 0 at constant speed cuz u r not changing ur speed but idk how to describe the graph

Answer 7

ok as he climb there are velocity in Y and X and only X at level

Answer 8

@AJ01

Answer 9

what does this part show does that mean the hiker is climbing gentle slope or steep incline?

Answer 10

i believe its gentle slope but not sure :/

Answer 11

in the original graph is gentle slope

Answer 12

then i think the answer is B

Answer 13

V is a constant but but not Vx or Vy

Answer 14

i don't know!

Answer 15

k thanks for helping :)

Answer 16

it is B...... i just red the choices

Answer 17

YW

Answer 18

oh okayy :)
