When some volcanoes erupt, big rocks have been measured to shoot upward with speeds of about 1000 m/s. Show that, neglecting air resistance, these rocks reach heights exceeding 50km.

Are all these for an exam or something?

To quote one of our very good math and science tutors: “You will find here at Jiskha that long series of questions, posted with no evidence of effort or thought by the person posting, will not be answered. We will gladly respond to your future questions in which your thoughts are included.”

no these are not an exam. I am a 40 yr old single mom trying to understand a class that I have not taken in 20 years. I would like to find someone to help me.

Then it would help the tutors know what you need if you let them know. As it is, these posts look as if you want someone to do them for you.

Please let them know what you know and what you need help with. If you post your question AND what you know about solving it, even if you don't think it's much, you're much more likely to get help from a tutor who knows physics.
