A goalie moves in a straight line and her velocity is described by the graph shown. How far away is the goalie at the time t=2.0 from where she was at t =0?
The description of the velocity/time graph:
initial velocity is 3.0 m/s and increases to 4.0 m/s in 1.2 seconds (slope m =1/(1.2)). From 1.2 seconds to 2 seconds, the velocity decreases to 0 (the slope seems to be m= -2)
Displacement = area of undercurve.
The Attempt at a Solution
I was given the graph, so i thought displacement would be to find the area under the lines...but apparently not.
I subtracted the area that forms the square and the triangle to find the displacement and got 2.6 m/s
Can someone please tell me what I did wrong?! :(
