Acceleration due to gravity is approx 9.8 metres/second2 So after 2.3 seconds, the velocity of the rock is 9.8*2.3 = 22.54 metres/second
Regardless of the height from which it is falling, (neglecting air resistance) it's speed will be 19.62 metres per second. (Acceleration from gravity is 9.81 metres per second squared, so after 1 second it is moving at 9.81 metres per second and after 2 seconds it is moving at 19.62 metres per second.

The net force on a 7 pound object that is falling (accelerating down) is 7 pounds. If it is not falling or moving at a constant speed, it is zero.
