First you want to use the SUVAT equation v=u+at You want to find a so you plug the values in a=(v−u)/t Since the car accelerates uniformly , u=0m/s and you are given the other values After finding the acceleration using SUVAT, just use F=ma to find the force required.
I would assume you are in first year A-levels. You should take a quick look through the 4 (5 if you count the last one I mention) and try to memorise them ASAP and the derivations.
1) v = u + at 2) s = (u+v)/2 * t 3) s = ut + 1/2(at^2) 4) v^2 = u^2 + 2as 5) s = vt - 1/2(at^2)
SUVAT is a commonly used term for the equations of motion. When you rearrange v = u + at, you get a = (v-u)/t, but since the car starts at rest, u = 0, so a = v/t.

I didn’t know about SUVAT but since it’s been explained it’ll be really useful for me, so thank you! I actually struggle with physics the most out of biology and chemistry, but I feel like it’s getting easier to handle... 🤔
Thanks! Would it be too early to start learning them in year 10?
From a Year 11, I definitely don’t remember this stuff, but if you really want to consolidate learning I think it’s useful to remember outside of your the topic you’re doing currently. I think it’s good practice to go over equations, especially for Physics
If you plan to do physics, there's no harm in having a look in the future content. Getting your head around the basic principles is always the best, then you can do a range of questions.
