Final answer:
The final speed of the truck is calculated using the formula v = u + at. Given the initial speed of 10 m/s, an acceleration of 3 m/s², and a time of 5 minutes (converted to 300 seconds), the final speed would be 910 m/s. However, this value is unusually high, so it's possible there is an error in the provided data or options.
Step-by-step explanation:
You're asking about the final speed of a truck after it accelerates from 10 m/s at a rate of acceleration of 3 m/s² for 5 minutes. To find the final speed, we use the formula v = u + at, where:
- v is the final velocity,
- u is the initial velocity,
- a is the acceleration,
- t is the time.
Given:
- Initial velocity (u) = 10 m/s,
- Acceleration (a) = 3 m/s²,
- Time (t) = 5 minutes = 300 seconds (since 1 minute = 60 seconds).
Insert these values into the formula:
v = 10 m/s + (3 m/s² × 300 s) = 10 m/s + 900 m/s = 910 m/s.
However, this final velocity seems unusually high. It would be best for you to recheck the time given or the acceleration to ensure the values make sense. If the values are correct, then the final speed of the truck is 910 m/s, which is not an option given in your multiple-choice answers. Therefore, there might be an error in either the options provided or in the given data.
