Physics · May / June 2021 · Paper 11 · Question 4

A coin falls from rest through the air and eventually reaches a constant speed. There is a resultant force acting on the coin due to the two forces P and Q shown in the diagram. [diagram: coin with upward arrow P and downward arrow Q] What happens to force P and what happens to the resultant force before the coin reaches constant speed?

1. Aforce P decreases, resultant force increases
2. Bforce P decreases, resultant force decreases
3. Cforce P increases, resultant force decreases
4. Dforce P increases, resultant force increases
