1. The problem statement, all variables and given/known data
A parachuter of mass 75 kg falls towards the earth at a speed of 25 ms-1. What is the resultant force acting on the person?

a. 750 N
b. 450 N
c. 1,350 N
d. No net force
e. 1,500 N


2. Relevant equations
F = ma


3. The attempt at a solution
I think the answer is (d) because 25 ms-1 is constant speed. Am I right?

Thanks
