Alice and Bob are standing at the middle of a level, perfectly balanced seesaw. Alice has a mass of 40 kg and Bob has a mass of 50 kg. If Alice starts to walk at 1m/s away from the center of the seesaw while remaining on it, how fast should Bob walk so that the seesaw remains level? If you do not know what a seesaw is, feel free to use your computer to search online for illustrations.

A metal cannonball of mass m rests next to a tree at the very edge of a cliff 36.0 m above the surface of the ocean. In an effort to knock the cannonball off the cliff, some children tie one end of a rope around a stone of mass 80.0 kg and the other end to a tree limb just above the cannonball. They tighten the rope so that the stone just clears the ground and hangs next to the cannonball. The children manage to swing the stone back until it is held at rest 1.80 m above the ground. The children release the stone, which then swings down and makes a head-on, elastic collision with the cannonball, projecting it horizontally off the cliff. The cannonball lands in the ocean a horizontal distance R away from its initial position. (a) Find the horizontal component R of the cannonball’s displacement as it depends on m. (b) What is the maximum possible value for R, and (c) to what value of m does it correspond? (d) For the stone– cannonball–Earth system, is mechanical energy conserved…

The top edge of a rod of mass 2.80 kg is pivoted to a point on the ceiling. The rod is free to rotate about this pivot and the length of the rod is 40.0 cm. The rod is pulled to the right until it makes 27.0 degree with the vertical and then released from rest. At the same time a clay ball of mass 350 grams is moving to the right with a speed 160 cm/s. As soon as the rod reaches the vertical position (moving to the left), the clay ball hits the rod at the bottom and sticks to it. o search a. b.

Problem: Statics. A worker places an aluminum ladder on a horizontal concrete slab against a vertical wooden wall at 30 degrees from the vertical. The ladder has length L=5m and m=30 kg. The ladder's CM is at a third of the length up. Worker Bob has mass M-90 kg and intends to climb up the ladder. Simultaneously, worker Charlie has mass M-90 kg and operates a rope through a single pulley to hoist a pail of mass m=30 kg. The axle of the pulley is anchored to the ladder at A=0.3 m along the ladder from the top point. Charlie is pulling the rope down with enough force to hoist the pail at uniform velocity. The mass of the pulley and rope are negligible. The friction in the pulley axle is negligible. The ladder is equipped with rubber booties and a rubber top. The kinetic friction coefficients are: rubber on dry concrete 0.9, rubber on dry wood 0.9, aluminum on wet concrete 0.2, aluminum on wet wood 0.2. 30 30 a) Calculate the safety limit in terms of maximal height off the ground that Bob…
Tarzan, who has a mass of 80 kg, holds onto the end of a vine that is at a 12° angle from the vertical. He steps off his branch and, just at the bottom of his swing, he grabs onto his chimp friend Cheetah, whose mass is 40 kg. What is the maximum angle the rope reaches as Tarzan swings to the other side?
A small 15.0-g bug stands at one end of a thin uniform bar that is initially at rest on a smooth horizontal table. The other end of the bar pivots about a nail driven into the table and can rotate freely, without friction. The bar has mass 70.0 g and is 110 cm in length. The bug jumps off in the horizontal direction, perpendicular to the bar, with a speed of 15.0 cm/s relative to the table. What is the angular speed of the bar after the bug jumped.
