John is practicing juggling three balls at once. He determines that he can perform this act, so long as there is a 4 s interval between the time when a ball leaves one of his hands and the next ball in one of his hands. (seems like the wording is messed up)

a)How long must each ball be in the air before it returns to John's hand?

b) At what speed must John throw each ball upward for its travel to require the time you calculated for part (a)?

c)How high above John's hands must each ball go?

2. Relevant equations

V=Vo+at

X=Xo+Vot+1/2(a)(t^2)

V^2=Vo^2+2a(X-Xo)
