Homework Help: physics

Posted by Anonymous on Monday, November 5, 2012 at 6:23pm.

A massless spring of constant k =60.9 N/m is fixed on the left side of a level track. A block of mass m = 0.7 kg is pressed against the spring and compresses it a distance d, as in the figure below. The block (initially at rest) is then released and travels toward a circular loop-the-loop of radius R = 1.3 m. The entire track and the loop-the-loop are frictionless, except for the section of track between points A and B. Given that the coefficient of kinetic friction between the block and the track along AB is ěk=0.1, and that the length of AB is 2.3 m, determine the minimum compression d of the spring that enables the block to just make it through the loop-the-loop at point C. (Hint: The force exerted by the track on the block will be zero if the block barely makes it through the loop-the-loop.)
