distanceSolution:
Given that a toy car placed on the floor travels at a constant acceleration for 3 seconds reaching a velocity of 4v m/s, we have
It slows down with a constant deceleration of 0.5 m/s² for 4 seconds before hitting a wall and stopping. This is as shown below:
Thus, the velocity-time graph for the toy car is as shown below:
The total distance traveled by the toy car is evaluated by calculating the area of the triangle ABC. Thus,
[tex]\begin{gathered} \text{Total distance traveled = }\frac{1}{2}\times7\times4 \\ =14\text{ meters} \end{gathered}[/tex]
Hence, the
