Question

A car travels at a constant speed of 15 m/s for 2 minutes. The car increases its speed from 15 m/s to 25 m/s during the next minute and travels at a constant speed of 25 m/s for 2 more minutes. which if the following graphs best represent the car's motion during this 5 minute period?​

Answer 1

Answer:

Graph F.

Explanation:

From the question given above, the following information were obtained:

1. The car travelled at a constant speed of 15 m/s for 2 minutes. This implies that the car is already moving and the graph can not be drawn from the origin.

Therefore, graph G is wrong.

2. The car increases its speed from 15 m/s to 25 m/s during the next minute and travels at a constant speed of 25 m/s for 2 more minutes.

This implies that the graph of the motion will project upward.

Therefore, graph H and J are wrong.

From the illustrations above, graph F gives the correct discription for the motion of the car.
