Babe Ruth steps to the plate and casually points to left center field to indicate the location of his next home run. The mighty Babe holds his bat across his shoulder, with one hand holding the small end of the bat. The bat is horizontal, and the distance from the small end of the bat to the shoulder is 25.5 cm . The bat has a mass of 1.00 kg and has a center of mass that is 70.0 cm from the small end of the bat.

To get up on the roof, a person (mass 70.0 kg) places 6.00-m aluminum ladder (mass 10.0 kg) against the house on a concrete pad with the base of ladder 2.00 m from the house. The ladder rests against a plastic rain gutter, which we can assume to frictionless. The center of ladder is 2.00 m from the bottom. The person is standing 3.00 m from the bottom. Find the normal reaction and friction forces on the ladder at its base.
A uniform plank of length 2.00 m and mass 30.0 kg issupported by three ropes, as indicated by the blue vectors inFigure P8.27. Find the tension in each rope when a 700.-Nperson is d = 0.500 m from the left end.
The forearm of length Larm=35.4 cm shown in the figure is positioned at an angle θ with respect to the upper arm, and a 5.30-kg ball is held in the hand. The total mass ?totalmtotal of the forearm and hand is 3.00 kg, and their center of mass is located at LCM=14.6 cm from the elbow. The biceps muscle attaches to the forearm at a distanceLbiceps=3.5 cm from the elbow. What is the magnitude of the force Fbiceps that the biceps muscle exerts on the forearm for ?=49∘? What is the magnitude of the force Fjoint that the forearm exerts on the elbow joint for ?=49∘?

A tightrope walker is walking between two buildings holding a pole with length ?=15.5 m, and mass ??=19.5 kg. The daredevil grips the pole with each hand a distance ?=0.575 m from the center of the pole. A bird of mass ??=525 g lands on the very end of the left‑hand side of the pole. Assuming the daredevil applies upward forces with the left and right hands in a direction perpendicular to the pole, what magnitude of force ?left and ?right must the left and right hand exert to counteract the torque of the bird?

In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tree 15 m away, as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?
