Question
An object is dropped from rest. Air resistance is not negligible. What is the acceleration of the object at the start of the motion?
A. Zero
B. Increasing
C. Decreasing
D. Constant
Markscheme
C
Examiners report
The clear statement that “air resistance is not negligible” indicates that the object has been released (otherwise it would be redundant), so C is the only possible answer.
