4.A car traveling 23 mi/h accelerates to 46 mi/h and 5 Seconds.It maintains that speed for 5 seconds and then slows to a stop in 5 seconds which graph shows the car speed over time?

Dirty steve
Yeahhhh dirty steve
well, it will look like a trapezoid truncated on the left.
To determine which graph shows the car's speed over time, let's analyze the given information step by step.
1. The car starts at a speed of 23 mi/h.
2. It accelerates to a speed of 46 mi/h in 5 seconds.
3. It maintains that speed for 5 seconds.
4. Finally, it slows down and comes to a stop in an additional 5 seconds.
Based on this information, let's analyze the options:
Graph A: This graph would show a constant speed of 23 mi/h for the entire duration. It does not represent the car's acceleration, maintaining speed, or deceleration accurately.
Graph B: This graph represents the car's journey accurately. It shows a linear increase from 23 mi/h to 46 mi/h over 5 seconds, a flat line representing the constant speed of 46 mi/h for the next 5 seconds, and then a linear decrease from 46 mi/h to 0 mi/h over the final 5 seconds. Graph B correctly reflects all the given information.
Graph C: This graph starts at a speed of 23 mi/h and then quickly drops to 0 mi/h. It does not consider the acceleration to 46 mi/h or the constant speed phase.
Therefore, the correct graph that shows the car's speed over time is Graph B.
