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.

Do Chapter 12, Problem 26. This is one way to measure a person's center of mass. She lies on a plank on two scales: one at her head, the other at her feet. They are 1.89 meters apart. Her head scale reads 433 N, and her foot scale reads 341 N. How far from her feet is her center of mass?
A nucleus that captures a stray neutron must bring the neutronto a stop within the diameter of the nucleus by means of thestrong force. That force, which “glues” the nucleus together, is approximatelyzero outside the nucleus. Suppose that a stray neutronwith an initial speed of 1.4 * 107 m/s is just barely captured by anucleus with diameter d = 1.0 * 10-14 m. Assuming the strongforce on the neutron is constant, find the magnitude of that force.The neutron’s mass is 1.67 * 10-27 kg.
