You pull on a string with a horizontal force of magnitude Fyb = 44 N that is attached to a block of mass mb = 6.1 kg, then to the axle of a solid cylinder of mass mc = 4.7 kg and radius r = 0.4 m, then to a spring of spring constant k = 135 N/m. This is all done on an inclined plane where there is friction ( μs = 0.61 and μk = 0.34 ), and the incline angle is θ = 30 degrees. Everything starts at rest, and the spring is unstretched. The block slides down the plane, the cylinder rolls down the plane (without slipping), and the spring stretches. How far have you pulled the block and cylinder when everything stops? The velocity when it has traveled 44 cm down the plane is 2.030 m/s.

From the step ladder shown in the figure, sides AC and CE are each 2.44 m long and hinged at point C. Bar BD is a tie-rod 0.762 m long, halfway up. A man weighing 845 N climbs 1.8 m along the ladder. Assuming the floor is frictionless and neglecting the mass of the ladder, find the tension (in N) in the tie-rod.
The coefficient of friction between mass m 1 and the surface is 0.15. The pulley is a disk and has a radius of 0.100 m and a mass of 0.25 kg. m 1 = 10.0 kg, m 2 = 20.0 kg.If the system is released from rest, find the final speed of each block when the hanging mass falls 2.0 m. ( I(disk)= 1/2 m R 2 )
Two masses each 2.2 kg are connected to each end of a massless rod oflength 1.00 m. A light string attached to the center of the rod holds therod and masses in equilibrium horizontally. A wad of clay (mass 123 g)is thrown vertically upward with a speed v = 2.7 m/s towards the mass onthe right. The clay collides with the mass and sticks to it. The system isfree to rotate in a vertical plane (ignore friction) To what angle will the system rotate before it momentarily stops?

Hungarian Adrian Annus won the gold medal for thehammer throw at the 2004 Olympics in Athens with a winningdistance of 83.19 meters.* The event consists of swinging a16-pound weight attached to a wire 190 centimeters long ina circle and then releasing it. Assuming his release is at a 45°angle to the ground, the hammer will travel a distance ofv02/gmeters, where g = 9.8 meters/second2and v0 is the linearspeed of the hammer when released. At what rate (rpm) washe swinging the hammer upon release?
