A toy car runed off the edge of a table that is 1.225m high. If the car lands 0.400m from the base of the car to fall,
a)how long does it take the car to fall
2(1.225)/-9.80=-0.25=0.5s
b)what is the horizontal velocity of the car?

    Actually, the time to fall is
    T = sqrt (2H/g).

    That seems to be what you did, but you were incorrect in writing
    -0.25 = .50
    Also since you are measuring distance down, forget the minus sign.

    Once you get the time T, use
    T = D/Vx to get the horizontal velocity, Vx.
