Dear Student,

We Know the first equation of motion:                     v=u+at here,  u=20 m/s  t=5 sec  v=0 m/sPutting in equation:0=20 + 5aa=-205=-4m/s2
Now, using third equation of motion:                   v2=u2+2asputting the values:                  02=202+2×(-4)s                  8s=400                  s=4008=50 m
