A point moves along a circle. Determine the radius of the circle if at the time when the speed of v = 10 m / s, the acceleration vector and the velocity vector equal in absolute value of 1.2 m / s, an angle of 30 °.

Right after the payment you will receive a link to a zip archive with the solution of the problem 7.8.5 (Chapter 2 - Kinematics, theme - 7.8: Accelerating the point at the back of the natural method of movement) in theoretical mechanics from the collection of short tasks Kep OE, JA Viba, OP Grapis, JA Svetinysh and others. Publishing Moscow / Graduate School / 1989, 2009, 2012. The task is made in the format word (typed or hand-written decision in a Word) or in manuscript form in the format gif, packed to the archive zip (open on any PC) .After checking the solutions would be very grateful if you leave your positive feedback.
