The answers A, this is because Ice is originally water and when water goes below it's freezing point it turns into ice
Distance of fall from rest,
without air resistance = (1/2) (gravity) (time)²
= (1/2) (9.8 m/s²) (95 sec)²
= (4.9 m/s²) (9,025 sec²)
= 44,222.5 meters .
The depth of the mine shaft is five times the height of Mt. Everest !
B. By vibrations in wires or strings
The study of motion is called kinematics.
