a steel ball dropped from a helicopter, and after 4s its acceleration is 8m/s. with freefall given iirs physics definition, the body
A. Definitely not free falling
B. is likely free falling but there's insufficient information given
C. It's not likely free falling
To determine whether the steel ball is free falling, we need to compare its acceleration with the defined value of acceleration due to gravity in free fall.
In free fall, the acceleration of an object is approximately 9.8 m/s² (near the surface of the Earth). Since the steel ball's acceleration is given as 8 m/s², which is significantly less than 9.8 m/s², we can conclude that the steel ball is not free falling.
Therefore, the correct answer is:
A. Definitely not free falling.
