The point moves along a circle of radius R = 7 m according to the equation s = 0,7t2. Define coordinate s at the time point when it is AN = normal acceleration of 3 m / s2.

Right after the payment you will receive a link to a zip archive with the solution of the problem 7.7.20 (Chapter 2 - Kinematics, theme - 7.7: Average acceleration point) 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.
