Question

How long does it take a jet to accelerate from 250 m/s to 430 m/s with a constant acceleration of 50 m/s squared?

Answer 1

The jet takes 3.6 seconds to increase its velocity from 250 m/s to 430 m/s with a constant acceleration of 50 m/s squared.

Step-by-step explanation:

The student is asking about the time it takes for a jet to accelerate from an initial velocity (v0) of 250 m/s to a final velocity (v) of 430 m/s with a constant acceleration (a) of 50 m/s2. We can use the kinematic equation v = v0 + at to solve for the time (t).

Here is the step-by-step explanation:

1. Start with the formula: v = v0 + at.
2. Plug in the given values: 430 m/s = 250 m/s + (50 m/s2)t.
3. Solve for t: t = (430 m/s - 250 m/s) / (50 m/s2).
4. Calculate the result: t = 180 m/s divided by 50 m/s2 = 3.6 seconds.

Therefore, the jet takes 3.6 seconds to increase its velocity from 250 m/s to 430 m/s given a constant acceleration of 50 m/s2.
