Impulsive Force Model Worksheet 2: Quantitative Conservation of Momentum Name: ______________________________________ 1. Kim holds a 2.0 kg air rifle loosely and fires a bullet of mass 1.0 g. The muzzle velocity of the bullet is 150 m/s. Find the recoil speed of the gun. Momentum conservation equation: Recoil speed =________________ 2. If the girl in the previous question holds the gun tightly against her body‚ the recoil speed is less. Calculate the new recoil speed for the 48 kg girl

INTRODUCTION In hydroelectric power plant‚ turbine been used to generate power from reservoir of water. Turbine been selected by their characteristic curves based on the potential energy available in the water and the amount of power to be generated. Turbine is a type that develops torque by reacting to the pressure or weight of a fluid. The operation of reaction turbine can be describes by the Newton’s third law of motion that is for every action‚ there is an equal and opposite reaction. In this

Purpose: During our lab‚ Galileo’s Water Clock‚ we created our lab to describe the motion of a ball on a plane using the water clock as an alternative method for measuring time. Our main purpose in this lab was to determine if the displacement of the ball is determined by the time or the time squared. Procedure: Once the water clock was set up‚ a ball was let go from the ramp at various distances for three trials each. Once the ball was let go‚ the water clamp was opened and then immediately

Coil Springs The springs in your suspension system‚ along with your struts and shocks‚ all work to reduce road impact‚ spread the weight of your vehicle‚ and keep all four of your wheels in contact with the ground. How tightly would the springs are and the rigidity of the suspension springs can also have an impact on your vehicle’s handling and performance. Torsion bars and leaf springs are often found on trucks‚ utility and heavy-duty vehicles‚ as well as automobiles that are older than 1985.

When discussing Isaac Newton the first thing that comes to mind is what a great scientist he was. While researching for this paper I learned there was so many other interesting facts in the life of Sir Isaac Newton. Isaac Newton was born December 25th 1642 in Lincolnshire‚ New England. (This date was later changed to January 4‚ 1643 when the Gregorian calendar was adopted in England.) Newton’s parents were Isaac Newton and Hannah Ayscoug. Newton’s father passed away in October 1642‚ three months

Research question: How does the mass of a muffin cup affect the velocity of the muffin cup? Variables: Independent The mass of a muffin cup‚ grams [g]‚ m Dependent The time it takes for the muffin cup to reach the floor‚ seconds [s]‚ t Controlled Air resistance‚ Newton [N]‚ FA Distance of releasing the muffin cup‚ meters [m]‚ d Reaction time‚ seconds [s]‚ t Method for controlling variables: Air resistance will be controlled by having the same shape of the muffin cup for all tests

CRA Launch We having been learning more and more about the angles‚ energy‚ and more for when we are building our catapult and how it would launch. We would need the angles that we will launch from and the energy we have for the catapult. Also the kind of energy we will be using to launch the catapult is kinetic energy. The angles we have for the launch are 25° and 32°. So based on our background knowledge‚ the question for this would be‚ which angle will the object travel fastest? For the hypothesis

KINEMATICS REVIEW LESSON EXAMPLE 1: Consider the velocity vs. time graph below. The motion of five different people (A‚ B‚ C‚ D‚ and E) are shown on the graph. Study the graph and answer the following questions. Some questions may have more than or less than one answer. Question: 1. Which person(s) changes direction during the time of motion? 2. Which person(s) is/are not moving? 3. Which person has the greatest average speed? 4. Which person(s) has/have a constant‚ positive acceleration
