Impulse and Momentum lab

Document Content and Description Below

Learning Objectives: 1. Understanding force vs time curves for a collision. 2. Calculating impulse using force vs. time curves. 3. Understanding the relationship between impulse and momentum. 4. A... pplying conservation of momentum for inelastic collisions. Apparatus: Aluminum track, track legs, two smart carts, two cart stops, and small black rectangular cart masses. Part A: Collision of a moving cart with a fixed cart Cart stop cart 1 stationary cart cart stop Consider the set up shown above. Cart 1 (mass m1) moves to the right and collides with the stationary cart 2 (mass m2). Just before the collision cart 1 is moving with velocity ???. (Pay attention to cart +x direction when place the carts) 1. What are the magnitude and direction of the momentum of cart 1 before the collision? Use an arrow to indicate the direction. Magnitude of ?⃗⃗⃗1 ⃗⃗? = |?⃗⃗⃗1 ⃗⃗?| = m1vxi Direction of ?⃗⃗⃗1 ⃗⃗? : positive X axis 2. If the cart bounces back with velocity ???, what are the magnitude and direction of the momentum of cart 1 after the collision? Magnitude of ?⃗⃗⃗1⃗⃗⃗? = |? ⃗⃗⃗1 ⃗⃗⃗?| = m1vxf Direction of ?⃗⃗⃗1⃗⃗⃗? : negative X axis 3. What are the magnitude and direction of the change in momentum of cart 1? Magnitude of ∆⃗⃗⃗⃗?⃗⃗⃗1 = |∆⃗⃗⃗⃗?⃗⃗⃗1| = m1vxf+m1vxu Direction of ∆⃗⃗⃗⃗?⃗⃗⃗1 : negative X 4. What is the direction of impulse on the moving cart? To the right or to the left, indicate with an arrow: 5. What is the direction of the impulse on the stationary cart? To the right or to the left, indicate with an arrow: [Show More]
