Question

Hello I need help with A please make it easy and simple to understand

Answer 1

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,

`\begin{gathered} \text{Total distance traveled = }(1)/(2)*7*4 \\ =14\text{ meters} \end{gathered}`

Hence, the
