Class Exercise 4

Problem 4:

It seems to me as if the direction of acceleration caused by gravity and acc. caused by drag in the y-axis should not be in the same direction (as shown in the solution). Can
anybody help me understand this? it wont affect the final answer too much

They aren't in the same direction. Note that:

\(f_y=-\gamma v_y\)

is directed opposite to the velocity.
