Mass of car, m = 1000kg
velocity, v = 5 m/s
radius, r = 25 m

The friction provides necessary centripetal force. So friction is equal to the centripetal force.

f =  \frac{mv^2}{r} = \frac{1000 \times 5^2}{25}=1000N

Minimum friction required is 1000N.

F=mv*v/r
f=1000*5*5/25
f=1000
force is 1000newtons
