Solution of the D1 in 13. After receiving the shock body starts to slide up on a rough inclined plane at an angle a = 20 ° to the horizon. The coefficient of sliding friction of the body of the plane f = 0,1. Determine the value of the initial velocity at which the path traversed by the body to stop, will be equal to s = 8,5 m.

Right after the payment you receive a link to the archive with the solution of the problem in theoretical mechanics D1 B13 (condition 13) 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.
