Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

A spring (spring1) of initial length L10 and spring constant kl is
hanging down the ceiling, with a ball (ball1) of mass m1 attached to
the bottom of the spring. Another spring (spring2) of initial length L
20 and spring constant k2 is hanging down from ball1 with another
ball (ball2) of mass m2 attached to the bottom of spring2. Use g to
denote gravity, t is time, L1 is the position of ball1 minus the ceiling,
L2 is the position of ball2 minus ball1, the velocity of ball1 is v1,
and the velocity of ball2 is v2. What is the expression of the net
force Fnet1 and Fnet2 acted upon ball1 and ball2?

You smuggle your bathroom scale on an amusment park roller coaster. At the top of a 16 m radius loop, you look down and note that you weigh 3 times your normal weight. At the bottom of the loop, you are gently brought to temporary rest by a spring that compresses 30 m before launching you around the loop backwards. Ignore friction and assume the mass of the car is 200 kg and the mass of just the rider is 50 kg. The track has negligible friction. What spring constant is needed for such ride?

The string passes over a small smooth pulley P which is fixed at the edge of a rough horizontal table. A is held at rest at a point 48 cm from P, and B hangs vertically below P, at a height of 47 cm above the floor. The coefficient of kinetic friction between A and the table is 0.27. It can be assumed that the particles will start to move when A is released.
