#"1860 m/s"#

Explanation:

Use this equation

#v = u + at#

Where

  • #v# = Final velocity
  • #u# = Initial velocity
  • #a# = Acceleration of rocket
  • #t# = Time taken to change velocity from #u# to #v#

#v = u + at = "0 m/s" + ["100 m/s"^2 × 0.31 cancel"min" × ("60 s")/cancel"min"] = "1860 m/s"#
