Answer:
sorry I hate when people press your question and answer with a fake answer for points, however you said it was 100 points and it's not even close lol but it is "your speed Is constant" that is not true
Answer:
d = 720 s
Explanation:
The question says, "A train initially traveling at 16m / s accelerates constantly at a rate of 2m / s2 in the same direction. How far will it travel in 20s?"
Initial speed, u = 16 m/s
Acceleration, a = 2m/s²
We need to find the distance covered by it in 20 seconds. Let the distance is d. Using the second equation of motion,

So, it will cover 720 m in 20 seconds.
Matter is anything that has mass and takes up space. Substances are types of matter that are pure. Just remember that matter has mass and they both start with "m." Substances are <u>types of matter</u>. Cheers, mimiisawesome5
