Given law of motion of a point along a path: s = 0,5t2. Determine the angle in degrees between the velocity vectors of points and total acceleration at time t1 = 3 s, where ρ = radius of curvature of 4 meters.

Right after the payment you will receive a link to a zip archive with a solution of 7.8.18 (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. Task completed in word format (handwritten or typed solution in 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 a positive review.
