Problem

A cat pushes a mouse horizontally on a frictionless floor with a net force of 1, point, 0, start text, N, end text for 3, point, 0, start text, m, end text.
How much kinetic energy does the mouse gain?
Round the answer to two significant digits.
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
start text, J, end text
