Conservation of Momentum

Printer Friendly Version
Momentum conservation for colliding balls, freight cars, and fish are worked out in the text book. Here we consider more collisions  In the tables below, fill in the numerical values for total momentum before, velocity after the collision, and total momentum after the collision for each two body system.
 
 
Bumper cars are fun!

Granny and Ambrose
 
Refer to the following information for the next two questions.

Granny whizzes around the rink and is suddenly confronted with Ambrose at rest directly in her path. Rather than knock him over, she picks him up and continues in motion without "braking."

Granny's mass = 50 kg
Granny's initial speed = 3 m/s
Ambrose's mass = 25 kg
Ambrose's initial speed = 0 m/s
BEFORE momentum
(kg m/sec)
  AFTER velocity
(m/sec)
