Problem

A volcano erupts, and a chunk of hot magma is launched horizontally with a speed of 208ms from a height of 94m. We can ignore air resistance.
What is the magma's horizontal displacement from the launch to when it hits the ground?
Round your answer to three significant digits.
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
