The velocity versus time data of a remote control car collected during a high school experiment is shown in the figure below. The car moves along a straight line. Initially, at t=0 s the car was located at x₀= 1.0 m.  Find the position, velocity, and acceleration of the car at t = 40 s.

• A. x (40s) = 120 m
  v_x (40 s) = 3 m/s
  a_x (40 s) = 0 m/s²
• B. x (40s) = 121 m
  v_x (40 s) = 4 m/s
  a_x (40 s) = 0.05 m/s²
• C. x (40s) = 130 m
  v_x (40 s) = 3 m/s
  a_x (40 s) = 0 m/s²
• D. x (40s) = 131 m
  v_x (40 s) = 4 m/s
  a_x(40 s) = 0.05 m/s²

Answer: (D)
