## Problem

A volcano erupts, and a chunk of hot magma is launched horizontally with a speed of 208, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction from a height of 94, start text, m, end text. We can ignore air resistance.
A volcano is erupting on the left side. A grey arrow extends horizontally from a red dot near the top of the volcano and curves downward to the ground on the right.
Two grey arrows cross to the upper left of the image. One points upward and is labeled "+y". The other points rightward and is labeled "+x".
What is the magma's horizontal displacement from the launch to when it hits the ground?
