Throwing a ball on the moon 2008-05-21
From leria:
equation for motion of moon is h=2.67t^2 + vt + s equation for earth h=-16t + vt + s

Suppose you are on an outpost on the moon and Jan is back on Earth. Both people toss a ball from a height of 96 feet with an initial velocity of 16 feet per second. How much longer will your ball stay in motion on the moon than Jan's on the earth?

Math Central,

I'm having a difficult time understanding which numbers to plug into the formula.

Calculer la hauteur de chute de cette pierre 2000-12-16
From Marcus:
Une pierre tombe au fond d'un puit, à 5 secondes on entend un son (de la pierre). Calculer la hauteur de chute de cette pierre en tenant compte de la vitesse du son = 340m.s-1

Il faut savoir que pour la chute libre v= g.t ; h = 1/2 g.t2 ; v = 2g.h

g intensité du champs de pesanteur = 10 ; h hauteur de chute.
