Solution of the D1 B7. Load mass m = 10 kg falls vertically on a parachute without initial velocity. The air resistance is proportional to the rate of R = -20v. Determine the velocity of the load at time t = 1 s.

Right after the payment you receive a link to the archive with the solution of the problem in theoretical mechanics D1 B07 (condition 07) in the test book "theoretical mechanics" Dievskaya VA Malyshev IA 2009 for university students.
The decision is decorated in a format word (typed or hand-written decision in a Word), packed to the archive zip (open on any PC).

After checking the solutions I would be very grateful if you leave your positive feedback.
