As shown in the figure, a 10.0 m long bar is attached by a frictionless hinge to a wall and held horizontal by a light rope that makes an angle θ with the bar. The bar is uniform and has a mass of 7 kg. What is the tension (T) in the rope when a 10.0 kg mass be suspended 4.2 cm from the hinge?

An object with a mass of 10 kg is initially at rest at the top of a frictionless inclined plane that rises at 80° above the horizontal. At the top, the object is initially 3.0 m high from the floor, as shown in the figure. When the object is released from this position, it eventually stops at a distance d = 13 m from the bottom of the inclined plane along a horizontal surface, as shown. Air resistance is negligible. Find the frictional coefficient (mu) between the horizontal surface. Is this friction static or kinetic?
