PRESENTED BY DANIEL LIN Mock Examination !!! 8. Flying Objects
Visualize – In Soviet Russia, guns shoot bullets. v(x), the speed of the bullet as a function of its position in the wall. L, the path length of the bullet within the wall. L
Visualize – Initial Conditions Moment of Entry Speed at Entry Moment of Exit Speed at Exit
Calculations Acceleration function: Separable! Use the initial conditions to find k! MAGIC !
Calculations Two initial conditions: And …
Calculations We now have the velocity function with respect to time… NOT GOOD ENOUGH! We need
More calculations… With every questions that you think you know the answer to. Ken wants you to learn modesty.
More calculations… Ken’s “Hint” Re-Write the original acceleration function: Separable & Solve
Almost done We already know When position x(0) = 0, the velocity is Solve for c MAGIC !
And v(x) is… Plug in the constant: Now we need to find L (The distance traveled during that 0.01 seconds.) We know the bullet exits the wall at
Conclusion Wouldn’t you like to know? That pakalolo plant ready for harvest?
Motion and Force A. Motion 1. Motion is a change in position
Changing the Phase of a Light Wave. A light wave travels a distance L through a material of refractive index n. By how much has its phase changed?
A particle moves along the x -axis so that its velocity at time t is given by At time t = 0, the particle is at position x = 1 (a) Find the acceleration.
Kinematics Examples A world class sprinter can burst out of the blocks to essentially top speed(of about 11.5 m/s) in the first 15 m of the race. What.
Acceleration Acceleration Velocity-time graph Questions.
T.H. The Professional Development Service for Teachers is funded by the Department of Education and Skills under the National Development Plan The Equations.
Kinematics- Acceleration Chapter 5 (pg ) A Mathematical Model of Motion.
Chapter 7 Projectile Motion. The motion of an object that has been thrust into air where the only forces acting on it are gravity & air resistance.
Vectors and scalars.
Solving Multiplication and Division Equations. EXAMPLE 1 Solving a Multiplication Equation Solve the equation 3x = x = 15 Check 3x = 45 3 (15)

CH 9 SEC 1 DESCRIBING MOTION GOAL/PURPOSE IN THIS SECTION STUDENTS LEARN HOW TO DESCRIBE MOTION USING TERMS DISTANCE, DISPLACEMENT, IN THIS SECTION STUDENTS.
Velocity and Acceleration. Velocity and Speed Velocity and speed are both how fast you are going, but velocity implies a direction (N, S, E, W) as well.
