Plzzzz answer fast its urgent!!!

Answer 1

Answer:

police will catch the thief if distance travel by policein time t=1250m.+25t m.

using s=ut+1/2 at^2

u=0,a=2m.s^2

(1/2)*2 t^2=1250+25t

t^2-25t-1250=0

(t+25)(t-50)=0

so t=50 sec.

Answer 2

Answer:

1250m

Explanation:

Use the second equation of motion fir the second part put t=50 and a=2
