    Im struggling to answer and understand this question please help.

    A particle is moving in a straight line with a constant acceleration covers 10m in 2 seconds and 22m in a further 2 seconds. How much further does it travel in the next two seconds?

    You can find the acceleration with suvat and simultaneous equations. You have 2 distances and 2 times.

    Yes but I did that and my answer dosent look right the distance is too big considering its only two more seconds?

    I got 34m in the next 2 seconds.
    Could you show me your method?

    well I used s=ut+1/2at^2

    in the first equation I used t=2 s=10
    in the second equation I used s=22 and t=4
    then i subsituted the answer for these into t=6
    Im guessing i made a mistake somewhere.

    10=2u+2a
    22=4u+8a
    20=4u+4a (times top one by 2)
    2=4a
    a=0.5
    u=4.5
    s=4.5*6+0.5*36*0.5=27+9=36m, walking through each step

    Thank youuuu i seee where i went wrong so in the end do you just do 36-22 to find out of much more the particle travelled
