The figure below represents part of the performance data of a car owned by a proud physics student. (The horizontal axis is marked in increments of 2 seconds and the vertical axis is marked in increments of 10 m/s.)
(a) Calculate the total distance traveled by computing the area under the red-brown graph line. In kilometers.
a = (ΔVx)/Δt
Speed = Total distance/Total Time
The Attempt at a Solution
I tried to use the trapezoidal method and break it up into 5 increments as I haven't learned how to integrate yet.
1/2*(f(0) + 2*f(1) + 2*f(2) + 2*f(3) + 2*f(4) + f(5) )
1/2*(f(0) + 2*f(33) + 2*f(50) + 2*f(50) + 2*f(48) + f(0)) = 181 x 10-3 = .181 km
However the answer was a little bigger than what I got which was .375 kilometers.
