A steady, incompressible, two-dimensional velocity field is given by the following components in the x-y plane: u=1.85+2.05x+0.656y v=0.754−2.18x−2.05y . Calculate the acceleration field (find expressions for acceleration components ax and ay), and calculate the acceleration at the point (x, y) = (-1, 4). The acceleration components are ax = + x ay = + y Acceleration components at (-1, 4) are ax = ay =

Explanation:

The acceleration field is obtained by deriving the components in function of the time. That is to say:

Where and .

The velocity components at given point are, respectively:

Lastly, the acceleration components are found:

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
