http://prntscr.com/3ds7ul  hi can help me the question is find the acceleration in the 1st 2 seconds in the graph.

anonymous · Answer

acceleration is the slope of a v-t graph

anonymous · Answer

yeah like the graph, Im being asked to find the value for acceleration in the 2 second mark can you help me

anonymous · Answer

first, do you know how to find the slope of a graph?

anonymous · Answer

yeah

anonymous · Answer

rise over run

anonymous · Answer

so is it 6.5 divided by 2?

anonymous · Answer

approximately 7/2 , because it's between 6 and 8

anonymous · Answer

umm so when you have that you take the middle number? so the answer would be 3.5 thank you so much

anonymous · Answer

can you help me one last question im being asked how many meters have been traveled in the 10 second mark how do i find that?

anonymous · Answer

now it's looking for the displacement. 
the area under the v-t graph is the displacement

anonymous · Answer

hmmm what are you mean exactly ?

anonymous · Answer

area*

anonymous · Answer

Divide the graph into triangles and rectangles, calculate the area of each and sum them up.
it comes to 89m
