Your result
Final velocity (v)
30 m/s
v = u + at
Key takeaway
u = 0 m/s, a = 3 m/s², t = 10 s → v = 30 m/s over 150 m

What this means
Final velocity (v) is 30 m/s. This result is a directional estimate based on the values you entered.
Is this good or bad?
A result is useful when the inputs reflect your real situation — re-run it as your numbers change.
What's the risk?
Estimates use standard assumptions; your actual outcome depends on the terms you are offered.
What should you do next?
Save or print this result, then confirm the key assumptions with an official source.
