traveled a total of 500 meters during this timeframe, how fast was it moving
initially?
I

Answer 1

Answer:

51.38m/s

Explanation:

displacement=initial speed×time+1/2acceleration×time^2

s=ut+1/2at^2

500=9.5u+1/2×2.5×9.5

divide everything by 9.5 and minus 2.5×1/2

500/9.5-1/2×2.5=u

u=51.38m/s

please give brainly.
