Does the presence of the snow increase, decrease, or leave unchanged the values of the impulse stopping the paratrooper and the average force stopping the paratrooper?

A. impulse unchanged, increased force
B. impulse unchanged, force unchanged
C. impulse unchanged, decreased force
D. decreased impulse, force unchanged
E. decreased impulse, decreased force
