force =ma
a. =(v-u÷t)
force =m(v-u÷t)
=m(0-90÷5)
=m(-90÷5)
=m(-45)
=200(-45)
= -9000
f. =-9000N
plz mark as brainlist answer plz

hey friend look ,.
Force=mass× acceleration
So it is obvious that we have to find acceleration first!
Now we know that v=u+at
put the values
=> 0= 90+ 5a( convert 90km/h into m/s by multiplying it with 5/18=> u will get 25m/s)
=> a= -5m/s^2
So force will be
-200×5=-1000N
