Data: Item | Value | Mass of Cart | 516g | Impulse | .35N | Velocity before | .343 m/s | Velocity after | -.318 m/s | Momentum before | .177 kg m/s | Momentum after | -.163 kg m/s | change | -.340 kg m/s | Questions: 1.Why is it desirable to have the same initial speed for each data run? If speed differs‚ the momentum will be effected. As velocity increases‚ momentum increases. 2.How will raising the end of the Dynamics Track give the cart the same

bullet of mass 10 g has a muzzle velocity of 300 m/s. Find (a) the momentum of the bullet (b) the recoil velocity of the gun if its mass is 2.0 kg. 3. A 70 kg man dives away from a stationary canoe with a velocity of 3.0 m/s parallel to the water. If the canoe has a mass of 150 kg‚ find its recoil velocity. 4. A steel sphere of mass 0.10 kg is fired horizontally with a velocity of 30 m/s into a block of plasticine of mass 1.0 kg at rest. With what velocity does the combination move away?

related basic laws. The same considerations will help you understand the motions of Earth satellites‚ of which there is one natural one and many artificial ones. Angular Measure Motion is described as a time rate of change of position. Angular velocity involves a time rate of change of position‚ which is expressed by an angle. It is important to be able to relate the angular description of circular motion to the orbital or tangential description‚ that is‚ to relate the angular displacement to

Introduction to Mechanisms Yi Zhang with Susan Finger Stephannie Behrens Table of Contents 1 Physical Principles This chapter introduces the basic physical principles behind mechanisms as well as basic concepts and principles required for this course. 1.1 Force and Torque 1.1.1 Force Force: an agent or influence that‚ if applied to a free body results chiefly in an acceleration of the body and sometimes in elastic deformation and other effects. Every day we deal with forces

the earth curves downward by approximately 5 metres over 8000 metres along the horizon‚ satellites launched with a horizontal speed of 8000 m/s can take orbit. At this speed‚ thanks to earth’s curved surface and a satellite’s constant horizontal velocity‚ the satellites‚ which are in free fall once projected‚ keep falling toward the earth‚ but always miss it. Thus‚ under the influence of gravity‚ satellites maintain motion in a circular pattern at a uniform speed. Most satellites are launched

Have you ever ridden on a rollercoaster and felt your heart drop as you were going downhill? Have you asked yourself how getting these feelings were possible? The answer is math. You may ask what math has to do with rollercoasters. Math is the reason for everything and anything that has to do with rollercoasters. Without math‚ it would be impossible to even be able to create one. To build a rollercoaster you need to be able to use numbers when talking about the costs‚ taking measurements‚ calculating
