What would be the final velocity of the van if it continued accelerating with the same rate for an additional 5 seconds?

To find the final velocity of the van, we need to know its initial velocity, the acceleration it experiences, and the time interval for which it accelerates. Without this information, it is not possible to give you a specific answer.

However, I can guide you on how to calculate the final velocity given these parameters:

1. Determine the initial velocity: The initial velocity of the van at the start of this 5-second interval should be known. If it is not provided, you need to have that data.

2. Determine the acceleration: The rate of acceleration experienced by the van must be known. This can be given as a value or can be derived from the information provided. If it is not given, you need to have that information.

3. Determine the time interval: The time interval for which the van continues to accelerate is given as 5 seconds.

4. Use the following formula to calculate the final velocity:

final velocity = initial velocity + (acceleration * time interval)

Plug in the values you have for the initial velocity, acceleration, and time interval to find the final velocity.

Remember to ensure your units are consistent (e.g., meters per second for velocity, meters per second squared for acceleration, and seconds for time) to obtain accurate results.
