## Homework Statement

This is a repost of a homework like question. The previous thread I did not understand.

In the assumption that drag is proportional to velocity, and when v = 20 m/s, a = 7.35 m/s^2, find the terminal velocity.

## Homework Equations

The thread stated that the equation most relevant would be ma = mg - kv.

## The Attempt at a Solution

I substituted all know values to make m(7.35) = m(9.8) - k(20), and attempted to solve, but the answer is 40 m/s.
