CHAPTER 5 MASTERING PHYSICS RESULTS
Problem 5.1
The three ropes in the figure are tied to a small, very light ring. Two of the ropes are anchored to walls at right angles, and the third rope pulls as shown. What are and , the magnitudes of the tension for
CHAPTER 6
Understanding Mass and Weight
Which of the following quantities represent mass?
g & kg
Which of the following quantities would be acceptable representations of weight?
lbs & kN
The gravitational field on the surface of the earth is stronger than
velocity-time
The longer the acceleration, the greater the change in velocity. If after a time velocity increases by a certain amount, after twice that time it should increase by twice that amount. Change in velocity is directly proportional to time when
PHYSICS TEST 2 STUDY GUIDE: CHAPTER 5: NEWTON'S LAWS (Equilibrium, Free Body Diagram) Q1:
The force up will be T2 and the force left will beT1. For the diagonal tension, you want to break it up into its x and ycomponents. The force right will be 100cos30
