Application of first order differential equations.

1. A body of mass 14.7 kg is released with an initial speed of 0.5 m/sec and finds a force due to the air resistance given by 8v2.

Find the speed for time = root of 2 seconds (t =√2 seconds)

The correct answer is = 4,23m/sec.

Please help me solving this step by step, because I'm studying for an important test tomorrow. Thank you so much.
