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.

An object of mass 120 kg is released from rest 480000 m above the ground and allowed to fall under the influence of gravity. Assume the gravitational force is constant, with g=9.8 m/sec2 , and the force due to air resistance is proportional to the velocity of the object with proportionality constant k= 3 kg/sec. Approximate the speed (in m/sec) of the object when it strikes the ground.
