In the derivation of the drill holes from the law of motion is as follows: Ho = 0, = 0 uO, zO = 4t, θ = 0, ip = 0, cp = 25e-t, where the point O lies on the axis of symmetry of the drill. At time t = 3 to determine in cm / s velocity of the drill point which is at a distance of 0.6 cm from the axis of rotation.

Right after the payment you will receive a link to a zip archive with the solution of the problem 10.3.4 (Chapter 2 - Kinematics, theme - 10.3: The general case of rigid body motion) in theoretical mechanics from the collection of short tasks Kep OE, JA Viba, OP Grapis, JA Svetinysh et al. 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.
