    P hysics 2 06 Example P roblems Newton’ s Laws of Motion Problem 1 . A) What is the direction of the acceleration of an object that is slowing down while heading northward? Answer : The acceleration would be southward since the net force required to cause this acceleration would be southward. The change in velocity is directed southward. B) What is the acceleration of an object thrown straight up in the air‚ near the surface of the earth‚ at the very top of its flight? Answer : The acceleration is

    INTRODUCTION The friction material in the automotive brake system has been considered as one of the key components for overall performance of a vehicle. This is because it plays crucial roles in various aspects of the brake performance such as a stopping distance‚ pedal feel‚ counter disk wear and brake induced vibrations. A great deal of effort has been given to improve the performance of the friction material and multiphase composites have been used as a brake friction material from the early

    you are right - I just don’t know! 1. Tension‚ Weight‚ Friction: You are taking advantage of an early snow to go sledding. After a long afternoon of going up and down hills with your sled‚ you decide it is time to go home. You are thankful that you can pull your sled without climbing any more hills. As you are walking home‚ dragging the sled behind you by a rope fastened to the front of the sled‚ you wonder what the coefficient of friction of the snow on the sled is. You estimate that you are

    N force? [1.45×103 J] 3. A rope making an angle of 35.0o drags a 10.0 kg toolbox a horizontal distance of 20.0 m. The tension in the rope is 60.0 N and the constant friction force is 30.0 N. What work is done by the rope? What work is done by friction? What is the resultant work? What is the coefficient of friction between the toolbox and the floor? [983 J‚ -600 J‚ 383 J‚ 0.472] 4. A box of mass 5.0 kg is accelerated by a force across a floor at a rate of 2.0 m/s2 for 7.0 s. Find

    the surface‚ the shorter the stopping distance and the larger the mass the further the stopping distance. Friction is the force which opposes the motion of one surface over another‚ and is the means through which a vehicle may move in a straight line‚ or may turn or stop. Stopping distances are affected by friction‚ the more friction the shorter the stopping distance‚ the lower the friction the further the stopping distance. A mass of an object is the fundamental measure of the amount of matter

    Questions What are the two ways that friction affected the performance of your vehicle? Friction affected my vehicle by either not pushing it far enough‚ or pushing it very far. The friction of the ground would also stop my vehicle from going farther then it could’ve. My car also needed a bit of momentum to start so the friction did not help my care move at all. What problems related to friction did you encounter and how did you solve them? The friction did not help my car move. My car needed

    2009 Kinetic Friction Experiment #13 Joe Solution E00123456 Partner - Jane Answers PHY 221 Lab Instructor – Chuck Borener Thursday‚ 11 AM – 1 PM Lecture Instructor – Dr. Jacobs Abstract In this experiment‚ we test factors which effect friction. We pulled a wood block across a surface to determine whether the surface area of the block or the type of surface effects friction. We found that the surface area of the block did not change the coefficient of kinetic friction‚ while the types of
