Answer:

  speed(u)=20m/s

                               velocity(v)=0

                                              v=u+at

                                              0=20-10(t)

                                               t=2s(time of acceleration)

                                               t=2s(time of retardation)

                                               u=0

                                               v=20m/s

                                               a=g=10m/s

                                                t=2s

                           distance=area covered

                                         =1/2x2x20+1/2x2x20

                                         =40m/s
