10.A 12.3 kg child jumps up and grabs a (round) horizontal tree branch that has a diameter of 6 cm. The child grabs the branch 28 cm from the trunk, and the weight of the child causes the branch to sag. If the shear modulus for the tree is 1.016 x 10⁶^N/_m2, how how much does the branch sag when weighted?

11.Ropes for rock climbing have a diameter of 10.5 mm and a Young's modulus of 8.72x10⁷ N/m². If a rock climber of mass 82.4 kg falls when there is 45.8 m of rope out, how far will the rope stretch?

A 3 kg ball is attached to a tree branch by a 2.0 m long rope. It is released from rest when the string is parallel to the ground. Just at it swings to its lowest point, it collides elastically head-on with a 2 kg ball of the same dimension, but going in the opposite direction. The 3 kg ball rebounds at a speed of 13 m/s after the collision. Find the speed of the 2 kg ball before the...

A 10 kg block on a horizontal surface is attached to a horizontal spring of spring constant k = 4.4 kN/m. The block is pulled to the right so that the spring is stretched 5.8 cm beyond its relaxed length, and the block is then released from rest. The frictional force between the sliding block and the surface has a magnitude of 38 N. (a) What is the kinetic energy of the block when it has moved 2.2 cm from...

A small block on a frictionless horizontal surface has a mass of 2.95×10−2 kg . It is attached to a massless cord passing through a hole in the surface. (See the figure below (Figure 1) .) The block is originally revolving at a distance of 0.295 m from the hole with an angular speed of 1.85 rad/s . The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0.140 m ....
