Question

A juggler tosses three balls alternately vertically upward. Each ball has an initial velocity of 5m/s. How high does each ball rise? How long does each ball remain in the air? Show your solution

Answer 1

$h=v_0^2/(2g)=5^2/(2\cdot9.8)=1.276\ (m)$ . Answer

$t=2t_0$

$v=v_0-gt\to t=(v_0-v)/g=(5-0)/9.8=0.51\ (s)$

$t=2\cdot0.51=1.02\ (s)$ . Answer
