Google Classroom

Problem

A monkey pushes a rock horizontally on a frictionless table with a net force of 10N for 2.0m.
How much kinetic energy does the rock gain?
Round the answer to two 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
