1. The problem statement, all variables and given/known data

can we measure time and accelaration at the same time?
what exactly acceleration operator is?

2. Relevant equations

heisenberg's uncertainity principle

3. The attempt at a solution

I guess acc. operator is dp/dt i.e. $$\frac{\partial^2 }{\partial t \partial x}$$(ignoring constants)
and $$\delta a \delta t$$ is <p>
which say we may not measure

To the first question one cannot answer in the context of quantum mechanics. The accelerator operator is

$$\hat{a}(t)=\frac{1}{m}\frac{d\hat{p}(t)}{dt}$$

in the Heisenberg picture.
