  1. PHYSICS CLASS ACTIVITY

  2. C.A.: Vo of Marble Launcher

  3. C.A. #6: Marble Launcher Vmuzzle • Determine muzzle velocity of launcher 3 ways: • 1) Vertical shoot • 2) Photogate timer • 3) Horizontal shoot

  4. Vo Vf a t d • Find: • Muzzle velocity C.A. #6: Marble Launcher Vmuz Method #1: Vertical Shoot • Measure: • Y max Vtop = 0 a = ? a = g ~ -10 m/s2 Vf = Vo + at d = Vot + ½ (at2) Ymax = ___ Vf 2 = Vo2 + 2ad up down up/down Vmuzzle Vimpact

  5. Photogate Timer Vmuz Photogate Light beam Marble Time ??? Overhead View

  6. C.A. #6: Marble Launcher Vmuzzle Method #2: Photogate Timer Vmuz diameter Photogate V= d/t diameter d = ? t = t photogate t = ? Vmuz = diameter t photogate

  7. Vf = Vo + at d = Vot + ½ (at2) Vf 2 = Vo2 + 2ad X Y Vo Vf a t d C.A. #6: Marble Launcher Vmuz Method #3: Horizontal Shoot Goal: Determine Vmuz Measure: Y, Range Vmuz Y= ____ Horizontal distance (X ) Vfx Q Vf Vfy

  8. Solve for Final Velocity of Horizontal Shoot Vfx Vfx = ____ Q Vfy = ____ Vf = ____ Vf Vfy Q = ___ SHOW CALCULATIONS CLEARLY!
