Eugenia and Bor stand at rest on roller blades as shown in the image below. Eugenia then pushes Bor with some constant force. Bor’s mass is 70 kg and Eugenia’s mass is 54 kg.   1)    State the hypothesis you are testing. The hypothesis should be the idea or general equations that are using to make the prediction.    2 ) Use the hypothesis to predict the ratio of Bor’s and Eugenia’s speeds after Eugenia pushed Bor.

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…

6. From a Kinetic Friction Experiment, calculate the coefficient of friction based on the following data, dexp acceleration (m/s?) M coefficient hanger mass (kg) Run block mass of friction (kg) 0.1322 Place answer below Run 1 0.1233 0.0700 (you must show the correct equation in symbolic form, and your work to receive full credit)

Please solve accurate and please give 100% correct justification of the answer. Thanks.
