If a rock is sitting on the ground and has a gravitational weight of 147 N, then solve for mass using F=ma.

However, the part about falling and hitting the ground makes it seem like something else is going on. This is not a well-worded problem.

F= Mass * Acceleration
147= mass * 9.81 m/s^2
Mass= F/acceleration
Mass= 147/9.81
Mass= 14.98 Kg

It depends how long it fell for.
