Learning Goal:
The velocity of any point B in a rigid body can be described by
VB = VA+WX IBA
where w is the angular velocity, IBA is the relative position vector
from point A to point B, and vA is the velocity of point A. Choosing
point A to have zero velocity, VA = 0, simplifies the equation to
VB=WXTBA
The point chosen such that the velocity is zero is called the

Learning Goal: To understand the concept of moment of a force and how to calculate it using a scalar formulation. The magnitude of the moment of a force with a magnitude F around a point O is defined as follows:Mo = Fdwhere d is the force's moment arm. The moment arm is the perpendicular distance from the axis at point O to the force's line of action. Figure F₁ 1 of 2 Part A A stool at a restaurant is anchored to the floor. When a customer is in the process of sitting down, a horizontal force with magnitude F₁ is exerted at the top of the stool support as shown in the figure. (Figure 1) When the customer is seated, a vertical force with magnitude F2 is exerted on the stool support. If the maximum moment magnitude that the stool support can sustain about point A is M₁ = 140 lb-ft, what is the maximum height do that the stool can have if the magnitudes of the two forces are F₁ = 65.0 lb and F₂ = 140 lb ?

Learning Goal: To use the principle of linear impulse and momentum to relate a force on an object to the resulting velocity of the object at different times. The equation of motion for a particle of mass m can be written as EF dv = ma = m dt By rearranging the terms and integrating, this equation becomes the principle of linear impulse and momentum: t2 ES F dt = m f dv = mv2 – mv1 V1 For problem-solving purposes, this principle is often rewritten as mvị +£ F dt = mv2 The integral F dt is called the linear impulse, I, and the vector my is called the particle's linear momentum. A tennis racket hits a tennis ball with a force of F = at – bt?, where a = 1200 N/ms , b = 500 N/ms? , and t is the time (in milliseconds). The ball is in contact with the racket for 3.05 ms . If the tennis ball has a mass of 62.6 g, what is the resulting velocity of the ball, v, after the ball is hit by the racket?
