Question
A 1-kg wood ball and a 5-kg lead ball have identical sizes, shapes, and surface characteristics. They are dropped simultaneously from a tall tower. Air resistance is present. How do their accelerations compare?
A. The 1-kg wood ball has the larger acceleration. B. The 5-kg lead ball has the larger acceleration. C. The accelerations are the same.
D. The 5-kg ball accelerates at five times the acceleration of the 1-kg ball.
E. The 1-kg ball accelerates at five times the acceleration of the 5-kg ball.
Explanation / Answer
The objects fall with the same acceleration in the influence of gravity regardless of there mass, shape, size and surface characteristics. so the correct option is 'C'
