You are watching: Your answer either contains an incorrect numerical multiplier or is missing one.

**Problem:**

**When a particle falls through the air, its early stage acceleration a = g diminishes until it is zero, and also thereafter it drops at a consistent or terminal velocity**

. Originally the particle drops from rest.My attempt:I used a ds = dv (*edit: i provided a dt = dv) and also came up with

. Originally the particle drops from rest.My attempt:

but on MasteringEngineering"s feedback, it states my price either consists of an incorrect numerical multiplier or is absent one. Am i doing the integral incorrectly?Thanks.

There"s a failure in my opened post. I offered a dt = dv rather of a ds = dt.Basically, ns took the integral that 1/(v_f^2-v^2) indigenous 0 to v_f/2 i beg your pardon is ln|3|, based turn off of: int dx/(a2 - x2) = <1/(2 a)> ln |(a + x)/(a - x)| + CSo I come out with (ln|3|)/gIs that correct?
