Two masses are connected by a string as shown in the figure below. Mass m1=3.7 kg rests on a frictionless inclined plane which makes an angle of 34 degrees with the horizontal, while m2=10.6 kg is held at a height of h above the floor. If m2 is released from rest and hits the ground with a speed of V=2.3 m/s, find the height m2 is released. h=? Please take g=9.80 m/s2.

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.
