Ответ:
Since the speed formula is = Distance / time
speed = distance /time
speed = metre/ seconds
speed = m/s
Ответ:
a) m/s- meters per second
Explanation:
Recall that m/s (meters per second) is the official derived SI unit for speed. That is, it is length (meters) over time (second), hence m/s.
It can't be joules (J), since that is the SI unit for work & energy.
It also can't be newtons (N), since that is the SI unit for force.
Therefore, the correct answer is a) m/s- meters per second.
I hope this made sense to you, if not, feel free to let me know and I can try to provide further assistance.
