The formual a=(u-v)/t applies to constant deceleration. The formula for constant acceleration is a=(v-u)/t
yes, this formuala only apllies to uniform acceleration. non - uniform acceleration can be represented by using a velocity-time graph.
The acceleration or deceleration can be represented by drawing tangents at the respective points on the graph and determining their gradients at these points.
Hope i've helped!

That formula does give the AVERAGE acceleration, under all circumstances. But, if by "a" you mean "the acceleration", as in it's a constant, then of course it only applies to cases of constant acceleration.

Yes. If velocity is a non-linear function of time, then you have to take the derivative of velocity as a function of time to get acceleration.
