Answer:
Vf = 9.622 m/s
Explanation:
Distance covered S=0.80m, Time t=0.087s and
g=9.81 m/s²
Required: Final velocity Vf when it hit the floor
Sol:
We have first find Vi so
Vi=Vit + 0.5 a t2
Vi =8.768m/s
Now Vf= Vi + at
Vf = 9.622 m/s
It could maybe be D which is the expansion of a liquid inside a closed tube
Answer:
Yes.
Explanation:
That is also a law violation.
B) The velocity of a car reduced from 50 km/h to 35 km/h over one minute. <span>B) The velocity of a car reduced from 50 km/h to 35 km/h over one minute. </span>
I’m pretty sure that it’s true. Hope this helps
