Question 11: When a force is applied to an object with mass equal to 1.00 kg, the acceleration of the mass is 3.25m/s2. (Assume that friction is so small that it can be ignored.) When the same magnitude force is applied to another object, the acceleration is 2.75m/s. What is the mass of this object? What would the second object's acceleration be if a force twice as large were applied to it? show your calculations.

4. A student feels a gravity force of 800 N from the Earth when they're sitting in this classroom. a. How big is the gravity force that the Earth feels because of the student? Explain. b. Two students discuss part a) Student 1: "The Earth is much heavier than the student, so its gravity must pull harder on the student than the student's gravity pulls on the Earth. The gravity force the Earth feels must be less than 800 N." Student 2: "That might be true, but I think that same 800 N would have less of an effect on the Earth than it would on a person. Using a = F/m, the acceleration the Earth feels might be very small from an 800 N force, because Earth is so heavy." Which of these students, if any, do you agree with? Justify your response with words and/or equations.

Analyzing Forces: Using Newton's 2nd Law A fireman has a mass of 75 kg. When the bell in the firehouse starts ringing, he slides down the pole with an acceleration of 3 m/s². What is the total force of friction acting on his body? 1. Identify the problem: What quantity are you being asked to find? What units will this answer be in? 2. Visualize and then sketch the problem. Draw arrows to illustrate the direction of the two forces acting on the fireman. Label these two forces by name. Do not use numbers yet. 3. These two forces act in opposite (+/-) directions and they will partially cancel. Assign the + value to the stronger force. The sum of these two forces is called the Net Force and it is the force which will actually move the fireman. Fill in the names of these two forces in the equation template below. (Hint: Remember that mass and weight are not the same.) Do not use numerical values yet: Net Force = + 4. Newton's 2nd Law gives us another equation for calculating Net Force: Net…
