NAME: ____________________________ DATE: _______________MOMENTUM CONSERVATION

MOM.2 – I can calculate the momentum of an object/system with direction and proper units.

MOM.3 – I can draw an interaction diagram and specify the system and the surroundings.

MOM.4 – I can draw and analyze momentum bar charts.

MOM.5 – I can use momentum conservation to solve different problems.

1. The pretty princess Pricilla (50 kg) is being pursued by a pack of perilous pirates. Pricilla is running North with a speed of 3 m/s. However, the large and lecherous pirate Larry (75 kg) is waiting behind a tree up ahead. In a surprise attack, Larry runs 3 m/s South into Pricilla and catches her.a. Draw an interaction diagram and identify system/surroundings for this situation.b. Create before and after momentum bar charts for this situation. You must label each bar.c. After Larry has picked up Pricilla, what will be their new velocity?d. Compare Larry’s momentum change to Pricilla’s momentum change as a result of this

interaction. Explain/justify your answer.e. Compare Larry’s velocity change to Pricilla’s velocity change as a result of this interaction.

Explain/justify your answer.

CV.4 – I can interpret/draw motion diagrams for objects moving with constant velocity.

CV.6 – I can interpret/draw the position vs. time graph for an object moving with constant velocity.

CV.7 – I can interpret/draw the velocity vs. time graph for an object moving with constant velocity.

f. Sketch a position-time graph, a velocity-time graph, and a motion diagram for Larry before and after the collision with Pricilla.

MOM.1 – I can determine whether interactions are present for a given situation by considering the motion of objects.

2. A spaceship far from all other objects uses its impulse power system to attain a speed of 104 m/s. The crew then shuts off the power. What will happen to the motion of the spaceship from then on? (Select all that apply.)

___ The spaceship will move in a straight line.

___ The spaceship will stop suddenly.

___ The spaceship will enter a circular orbit.

___ The spaceship will travel on a curving path.

___ The spaceship will gradually slow down.

___ The speed of the spaceship will not change.
