Textbook Question
Chapter 5.2, Problem 5.1CE
Because Newton’s first law is counterintuitive, it is important to take some time to think about what the law says and about how and why it differs from our intuition.
- a. Why did the unavoidable presence of friction make it difficult for earlier scientists to come to the conclusion expressed in Newton’s first law?
- b. What is the natural state of an object?
- c. How much force does it take to keep an object moving at constant velocity?

A woman has a mass of 55.1 kg on Earth.a. What is the woman’s mass on the moon? (2 Significant figures only, type in the first box)b. What would be the woman’s weight on the moon if the gravity is 1.67 ms21.67 ms2 . (3 significant figures only, type in the second box)
Do not include the units when writing your final answers in the box.
Why would a 1kg(2.2lb) rock and a 20 kg rock have the same acceleration when dropped? Use Newton’s Second Law in your explanation. Hints: a. The force causing the acceleration is the weight of the rock which equals its mass in kilogram X 9.8 m/s2. b. a=f/m
How much more force would you have to apply to a 30 kg block of cement compared to a 10 kg block of cement in order to achieve the same acceleration? Hint: Apply Newton’s Second Law.
Give a detailed explanation for both.

This force is just great enough to hold the object in place (to prevent it from sliding down the wall). If the coefficient of static friction between the object and the wall is μ = 0.27, then find the applied force.
