    you are given the initial speed which is 0 (because it started from rest) you are given distance which is 100 m you are given final speed which is 20 m/s then you're looking for acceleration therefore you can use the formula \[V_2 ^2 = V_1 ^2 + 2ad\] where V2 is final speed V1 is initial speed a is acceleration d is distance so now just substitute \[20^2 = 0^2 + 2a(100)\] \[400 = 200a\] divide both sides by 200 \[\frac{400}{200} = a\] \[a = 200 m/s^2\]

    uhmm oops..should be \[a = 2 m/s^2\] sorry haha
