h = ho.d - o.5g*t^2 = 0
4000 - 4.9t^2 = 0
-4.9t^2 = -4000
t^2 = 816.3
Tf = 28.6 s. = Fall time or time in flight.

Dx = Hor = 80m/s * 28.6s = 2286 m.

Talk slowly but think quickly

Spend some time alone

When you realize you've made a mistake, take immediate steps to correct it

BEGIN while others are procrastinating

COMMEND while others are criticizing

PREPARE while others are daydreaming

To handle yourself, use your head; to handle others use your heart.
