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

do you get it @Muskan ?
