Consider the image shown where a plank rests horizontally on a roof.Given the following parameters: M= 4.5kg L=9.8m, m=59kg and D=3.2m. Calculate the distance from the left end that a person would reach when the plank starts to tip.

In the figure, what magnitude of force F applied horizontally at the axle of the wheel is necessary to raise the wheel over an obstacle of height h = 0.267 m? The wheel's radius is r = 0.673 m and its mass is m = 1.75 kg. DF

A solid spherical ball starts from rest at an initial height of 1.7 m, and rolls down an incline. The ball's mass is 3.4 kg and its radius is 17.5 cm. What is the ball's final center of mass (translational) speed (in m/s)?

A physics experiment is set up using two pulleys, a string, and a weight as shown below. The larger pulley has a radius of 14 centimeters, and the smaller pulley has a radius of 8 centimeters. The distance between the centers of the pulleys is 56 centimeters. The string is pulled tightly across both pulleys so that F is a common tangent of the pulleys. Find the length of string from A to B to the nearest tenth of a centimeter. A weight O 56.0 cm O 22.0 cm O 55.7 cm O 58.5 cm

Determine the speed of the block with a mass of 0.60 kg after it has fallen 145 cm. The sphere is a shell with M = 4.5 kg and R = 8.5 cm. The pully has a rotational inertia of 0.0030 kg m2 and r = 5.0 cm. Use g = 9.8 m/s/s. Use conservation of energy.

A horizontal platform in the shape of a circular disk rotates on a frictionless bearing about a vertical axle through the center of the disk. The platform has a radius of 2.58 m and a rotational inertia of 255 kg·m2 about the axis of rotation. A 53.8 kg student walks slowly from the rim of the platform toward the center. If the angular speed of the system is 2.18 rad/s when the student starts at the rim, what is the angular speed when she is 1.79 m from the center?

A uniform plank of length 2.00 m and mass 27.5 kg is supported by three ropes, as indicated by the blue vectors in the figure below in each rope when a 725-N person is d = 0.500 m from the left end. magnitude of T, N magnitude of T, N magnitude of T, N 40.0° -2.00 m

Three children are trying to balance on a seesaw. The seesaw is 3.7 m long and pivots about a rock at its center. Louie and Laura are already sitting on opposite ends. If Martha weighs 29 kg, where should she sit so as to balance the seesaw?

The uniform solid block in the figure has mass 39.8 kg and edge lengths a = 0.902 m, b = 1.67 m, and c = 0.141 m. Calculate its rotational inertia about an axis through one corner and perpendicular to the large faces. Number:   Unit:

Three children are trying to balance on a seesaw.  The seesaw is 4.1 m long and pivots about a rock at its center.  Louie and Laura are already sitting on opposite ends.  If Martha weighs 33 kg, where should she sit so as to balance the seesaw?
