A 10.30-m ladder with a mass of 22.6 kg lies flat on the ground. A painter grabs the top end of the ladder and pulls straight upward with a force of 258 N. At the instant the top of the ladder leaves the ground, the ladder experiences an angular acceleration of 1.66 rad/s2 about an axis passing through the bottom end of the ladder. The ladder's center of gravity lies halfway between the top and bottom ends.

(a) What is the net torque acting on the ladder? N · m

(b) What is the ladder's moment of inertia? kg · m2

A ladder whose length L is 12 m and mass m are 45 kg rests against a wall. Its upper end is a distance h of 9.3 m above the ground. The center of mass of the ladder is one-third of the way up the ladder. A fire fighter whose mass M is 72 kg climbs the ladder until his center of mass is halfway up. Assume the wall but not the ground is frictionless. What forces are exerted on...

Suppose a ladder of length L = 8 m and mass m = 20 kg is leaning up against a wall such that it makes an angle of θ = 70 degree angle with the floor and is not moving. For this problem, we'll say there is no one standing on the ladder. As we did at the end of discussion, we'll also imagine that the ladder is up against a very smooth wall so that there is no frictional...

A uniform disk with mass m = 9.07 kg and radius R = 1.36 m lies in the x-y plane and centered at the origin. Three forces act in the +y-direction on the disk: 1) a force 313 N at the edge of the disk on the +x-axis, 2) a force 313 N at the edge of the disk on the –y-axis, and 3) a force 313 N acts at the edge of the disk at an angle θ =...

A box with 10 kg of mass slides down an inclined plane that is 1.7 m high and 3.5 m long. Due to friction the box reaches 3.0 m/s at the bottom of the inclined plane. Beyond the inclined plane lies a spring with 650 N/m constant. It is fixed at its right end. The level ground between the incline and the spring has no friction The box compressed the spring, got pushed back towards the incline by the spring....

A cylindrical rod of length 2.0 m, radius 0.5 m, and mass 1.5 kg has two spheres attached on its ends. The centers of the spheres are 1.0 m from the center of the rod. The mass of each sphere is 0.66 kg. The rod is capable of rotating about an axis passing through its center and perpendicular to the plane of the page, but the set up is stationary to begin with. A small mass of value 0.19 kgmoving...
