  1. ? m1, v1i m2, v2i ? Linear Momentum and Collisions Definition of momentum (vector) SI unit: kg m/s

  2. Newton’s second law in term of rate of change momentum

  3. Δt F Average force applied Fav m m after before What happens during a collision?

  4. 40m/s Vf=? Definition of impulse: SI unit: N*s, kg m/s Ex: Ball moving toward hit at 40m/s 0.2kg, hit 6500 N a ball for 1.3 ms. Find final speed of ball?

  5. collision Conservative of Momentum:

  6. 2 1 m2=20kg m1=16kg Person or canoe 1 push person or canoe 2 so that canoe 2 moves to right at 3m/s, find the velocity of canoe 1.

  7. Find the Velocity of the Bee A honeybee with a mass of 0.150kg lands on one end of a floating 4.75g popsicle stick. After sitting at rest for a moment, it runs toward the other end with a velocity vb relative to the still water. The stick moves in the opposite direction with a speed of 0.120 cm/s. What is the velocity of the bee? (Let the direction of the bee’s motion be the positive x direction)
