Explanation / Answer

        Given that the timetaken to reach the top of window t = 0.27s         Distancetravelled is S = 1.00 m ----------------------------------------------------------------------------    From the equation of motion S = Ut +(1/2)at2                                                 S= Ut - (1/2)gt2             Then we get U = --------- m/s    Time does the ball reappears is T = 2U /g                                                       =--------sec    The maximumheight reached by the ball is H =U2/2g                                                                       = -------- m
