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.

The system is situated such that the mass is on a frictionless, horizontal surface and the spring acts parallel to the surface. a) If the mass leaves the spring with a speed of 20.0 m/s, by how much was the spring initially compressed? b) What is the speed of the mass when the spring is halfway back to its equilibrium position?
A stick with a mass of 0.224 kg and a length of 0.416 m rests in contact with a bowling ball and a rough floor, as shown in the figure(Figure 1). The bowling ball has a diameter of 20.6 cm , and the angle the stick makes with the horizontal is 30.0 ∘∘. You may assume there is no friction between the stick and the bowling ball, though friction with the floor must be taken into account. Find the magnitude of the force exerted on the stick by the bowling ball. Find the horizontal component of the force exerted on the stick by the floor. Repeat part B for the vertical component of the force
Two blocks, which can be modeled as point masses, are connected by a massless string which passes through a hole in a frictionless table. A tube extends out of the hole in the table so that the portion of the string between the hole and M1 remains parallel to the top of the table. The blocks have masses M1= 1.9 kg and M2= 2.8 kg. Block 1 is a distance r= 0.35 m from the center of the frictionless surface. Block 2 hangs vertically underneath. How much time, in seconds, does it take for block one, M1, to make one revolution? Assume that block two, M2, does not move relative to the table and that block one, M1, is rotating around the table.

1. An inventor patents a "golf machine". It consists of a "golf club" which is really a pendulum of length L = 2 (m), with a massles string and a mass M = 30 (kg) on the end. By pulling back on the pendulum until the string makes an angle 0= 10° from the vertical, and then releasing it from rest, the golf club strikes the "golf ball" exactly horizontally. The golf ball is a mass m = that rests on a platform which is h = 20 (cm) above the horizontal ground. Assume that all collisions are elastic and all masses are point masses.
