    V1=0
    V2=0
    d=?
    t= 59 sec.

    v1+v2=O
    v=d/t
    v=0/50
    v=0 m/s

    v=d/t
    d=vt
    d=0(50)
    d=0 m

    Given:

    v1 (initial velocity) = 0 m/s

    t = 50s

    a = 9.8m/s2

    v2= ?


    Solution:

    Use kinematics formula v2 = v1 + at

    v2 = (0m/s) + (9.8m/s2) (50s)

    v2= 490m/s
