I have to take a final soon and I have practise questions The only one here I am having trouble with is thislast one. This question bugs me and the answer key doesn't show how to do it(adsbygoogle = window.adsbygoogle || []).push({});

After a model rocket reached its maximum height, it then too 5.0 seconds to return to the launch site. What is the approximate maximum height reachd by the rocket? {Neglect air resistance.}

the answer is 120 m

the only info u have is time and acceleration

How do I go about doing it?
