The average velocity is 23 m/s not 22.6m/s.
You are wrong by saying that x(0) is 0 since it really is "-4".
So, 226 - (-4) = 230
230/10 = 23m/s

Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.

  • Intro 0:00
  • Velocity and Acceleration 0:27
    • Particle moves In x Direction
    • Instantaneous Velocity for Δt =0
    • Acceleration (Change in Time) v(t+=Δt)-v(t) /Δt
  • Example 8:08
    • x(t) =(-4+3t+2t^2)
    • Finding Average velocity at 10sec
    • V at t=3s
    • x(t) =0 ,0.2 sin (2t)
    • Finding Velocity
  • Constant Acceleration 15:29
    • Object Moving with Constant Acceleration
    • Find Velocity and Position at Later Time t
    • v=∫a dt
    • V(t) =v0+at
    • v(t) =dx/dt x=∫vdt
    • T=v-v0/a
  • Extra Example 1: Velocity and Acceleration
  • Extra Example 2: Particle Acceleration
