A massless spring constant "k" is fixed on the left side of a leveltrack. A block of mass "m" is pressed against the spring andcompresses it a distance of "d". The block (initially at rest) isthen released and travels toward a circular loop-the-loop of radius"R". The entire track and the loop-the-loop are frictionless,expect for the section of track between points A and B. Given thatthe coefficient of Kinetic Friction between the block and the trackalong AB is "mk" and that length of AB is "L".
A) Calculate the speed "Va" of the mass as it passes point A interms of "d".
B) Calculate the speed "Vb" of the mass as it passes point B interms of "Va"
C) Calculate the speed "Vtop" of the mass at the top of the loop interms of "Vb"
D) What is the normal force on the mass at the top of the loop (interms of "Vb")?
