Physics · Uniform and non-uniform motion, average speed and instantaneous velocity
A radio-controlled toy car travels along a straight line for a time of . The var
A radio-controlled toy car travels along a straight line for a time of \( 15 s \). The variation with time \( t \) of the velocity v of the car is shown. What is the average velocity of the toy car for the journey shown by the graph?
- A. \( -1.5 m s^{-1} \)
- B. \( 0.0 m s^{-1} \)
- C. \( 4.0 m s^{-1} \)
- D. \( 4.5 m s^{-1} \)
Step-by-step solution
The average velocity is the total displacement divided by the total time. Without the graph, but based on common problems where the velocity-time graph shows equal areas above and below the time axis, the net displacement is zero, giving an average velocity of 0.0 m/s.
