(a) Given, u=0 a=0.1m/s-2 t= 120 sec (2 min) v=u+at v=0+0.1×120 v=12m (b) We have, u=0 a=0.1m/s-2 t=120 sec v=12m s=ut+1/2at-2 s=0×120+1/2×1/10×120×120 s=0+1/10×60×120 s=0×60×12 s=720m

Starting from rest it means initial position will be zero convert 2 minutes into seconds to find speed we can use the equation v=u+at v will be our speed to find distance we can use the equation S(distance)=ut+1/2atsquare. So thats how you can find solution
