A robotic bug is moving along the x-axis. Its equation of motion is x(t) = 10*t^2- 4*t - 6
I have a problem with only one question:
What is the distance covered by the bug between t = 0.1 s and t = 0.4 s?
The Attempt at a Solution
The first derivative of 10*t^2- 4*t - 6 is velocity: 20*t-4
So I integrated 20*t-4 and computed the value of the integral from 0.1 to 0.4. I got 0.3 and it is wrong. I have no idea why. :(
