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

Elastic collision
Two metal spheres, suspended by vertical cords, initially just
touch, as shown in Fig. 9-20. Sphere 1, with mass
30g, is pulled to the left to height h, = 8.0 cm, and
%3D
m1
then released from rest. After swinging down, it undergoes
an elastic collision with sphere 2, whose mass m, =
75 g.
What is the velocity v,of sphere 1 just after the collision?

collides with ball 2, which
then swings upward. If the
collision is elastic, no
