Question

Based on the graph of velocity over time, which could be the initial velocity and the final velocity for this graph?

initial = 0 m/s; final = 2.5 m/s
initial = 2.5 m/s; final = 2.5 m/s
initial = 3.0 m/s; final = 6.0 m/s
initial = 6.0 m/s; final = 3.0 m/s

Answer 1

I don't see the graph — could you upload it or describe the velocity at the leftmost (t = 0) and rightmost (final time) points?

How to decide: the initial velocity is the value of v at t = 0 (left edge of the graph); the final velocity is the value of v at the largest t shown (right edge). Match those two numbers to the choices:

- If v(t=0) = 0 and v(final) = 2.5 → choose "initial = 0 m/s; final = 2.5 m/s".
- If v(t=0) = 2.5 and v(final) = 2.5 → choose "initial = 2.5 m/s; final = 2.5 m/s" (constant).
- If v(t=0) = 3.0 and v(final) = 6.0 → choose "initial = 3.0 m/s; final = 6.0 m/s" (increasing).
- If v(t=0) = 6.0 and v(final) = 3.0 → choose "initial = 6.0 m/s; final = 3.0 m/s" (decreasing).

If you upload the graph or tell me the values at the left and right ends, I’ll pick the correct option.
