Chapter 0, Problem 5

(choose chapter or problem)

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." Consider both Granny and Ambrose as two parts of one system. Since no outside forces act on the system, the momentum of the system before collision equals the momentum of the system after collision. a. Complete the before-collision data in the table below. BEFORE COLLISION Granny's moss Granny's speed 80 kg 3 m1s Grannv's momentum Ambrose's mass 40 kg Ambrose's speed o m1s Ambrose's momentum Total momentum b. After collision, Granny's speed [increases] [decreases]. c. After collision, Ambrose's speed [increases] [decreases]. d. After collision, the total mass of Granny + Ambrose is e. After collision, the total momentum of Granny + Ambrose is f. Use the conservation of momentum law to find the speed of Granny and Ambrose together after collision.
