An electromagnetic rail gun (or Trebuchet) could easily chunk rocks at earth.

The Moon’s Gravity Well is so much smaller than the Earth’s.

Hitting a specific target is another matter, unless your rock has terminal guidance.

Call me when your trebuchet (or even your EMRail gun) can make 2.4 Km/sec
