Halliday Resnick Krane Chapter 2 Problem 30: Juggling Five Balls

[vibha_ganji]

Homework Statement

A juggler juggles 5 balls with two hands. Each ball rises 2 meters above her hands. Approximately how many times per minute does each hand toss a ball?

Relevant Equations

y= y0 + vt + (at^2/2)

If each ball rises two meters, then the time is in the air is equal to around 1.28 seconds. After this, what am I supposed to do? I feel really stuck. If all of the balls are released at different times, how am I supposed to find the answer?
