    Given : Initial speed , u = 0 m/s .

    Final speed , v = 8.7 m/s .

    Distance travelled , d = 32 m .

    To Find :  How far from the starting line will the sprinter be if they continue at the speed for 5 more seconds .

    Solution :

    It is given that after reaching speed of 8.7 m/s speed become constant .

    So , distance covered in 5 second is :

    d=v \times t\\d=8.7 \times 5 \ m\\d=43.5 \ m

    Now , total distance from start line is :

    D=32+43.5=75.5 \ m

    Therefore , the distance from starting line is 75.5 m .

    Hence , this is the required solution .
