Initial velocity(u)=50 m/s
final velocity (v)=0
time taken=10 sec
acceleration =rate of change in velocity=v-u
                                                           t
a=-50/10=-5m/s^2

Answer:
         Initial Velocity (u) = 50m/s
         Final Velocity v = 0
       time = 10 seconds
       Acceleration = ???
we know that ,
     v = u +at
   0 = 50 + a*10
   0 = 50 + 10a
or -10a = 50
or a = -5
