Physics 101- Introduction to Mechanics
April 10- Conservation of Momentum

 

 

 

 
 

 

  Impluse- transfer of momentum
 

Also, what is the transfer of momentum?  Recall that the transfer of energy was work which was related to forces and displacements.
 
 
 
 
 
 

  • A basketball is dropped vertically on a floor.  Make a sketch that shows the initial momentum of the ball as it first touches the floor and the final momentum at the instant the balls leaves contact with the floor.  Also, sketch the change in momentum.
  • What is the direction of the average net impulse acting on the ball during its contact with the floor?

 

A baseball of mass 150 g is pitched at a sped of 40 m/s and is then hit straight back to the pitcher at a speed of 60 m/s.  What impulse acts on the ball?  What average force did the bat exert if it was in contact with the ball for 5ms?
