Newton’s second law in term of rate of change momentum
Δt F Average force applied Fav m m after before What happens during a collision?
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?
collision Conservative of Momentum:
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.
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)
