Can someone explain these please?

Q1)

Suppose that the velocity v of a falling body, in some unit system, satises d1) 5:751}, and when t = 0, v = 4. Then we can solve that o = [E]. We can also solve for the terminal velocity. Notice that as t grows large, 1) approaches some limit, this limit is the terminal velocity. Calculate lim 1) = E]. tmo Challenge: Have a look at the general formula for 1: that you calculated in the previous question, and determine if how) the terminal velocity depends on the constants g, k and C .
