The manufacturer of a family car gives the following information

[Greg0986]

mass of car: 950kg
the car will accelerate from 0 to 33m/s in 11 seconds

calculate the acceleration of the car during the first 11 seconds

If you are struggling with your physics homework, you should mention it to your teacher.

[jake-the-peg]

the acceleration of a body is the rate at which its velocity change.

This is expressed in one of Newtons equations of motion - specifically

v=u+at

V is the final velocity (33m/s) here, u the initial velocity, 0 m/s and t the time 11 seconds

a gives you the acceleration in m/s²

The mass of the car is a red herring

[vascop]

Yes, but I wouldn't be surprised if the question had a second part which asked for the force required to produce this acceleration, and then of course the mass would be involved (force=mass X acceleration

I've noticed a tendency in GCSE papers to supply additional data to test whether candidates can seperate information that they need from extraneous information.

Quite a good idea actually because this is a key skill
