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

The only force acting on an object of mass 2.00 kg moving along the x-axis is shown in the figure. If the speed vx is +2.0 m / s at t = 0, what is the speed at t = 4.0 s?

A purple beam is hinged to a wall to hold up a blue sign. The beam has a mass of mb = 6.2 kg and the sign has a mass of ms = 17.1 kg. The length of the beam is L = 2.51 m. The sign is attached at the very end of the beam, but the horizontal wire holding up the beam is attached 2/3 of the way to the end of the beam. The angle the wire makes with the beam is θ = 33.6°. 1) What is the tension in the wire? N 2) What is the net force the hinge exerts on the beam?
