IMPULSE AND MOMENTUM

1. 1. A car collided with a bus that has greater mass and velocity than the car. Which of these describes the change of momentum of the bus and the car?

• The change of momentum of the bus is less than that of the car.

• The change of momentum of the bus is greater than that of the car.

• The change of momentum of the car and the bus is the same.

• The change of momentum of the car and the bus is zero.

2. A mini dump truck full of abaca fiber collides with a motorcycle or habal-habal. The  

          velocity of the truck and the motorcycle is the same. Which has a greater impulse? Why?

• The mini dump truck because it is full of abaca fiber.

• The mini dump truck because it has larger change in momentum.

• The motorcycle because it has larger change in momentum.

• The motorcycle because it has lesser mass.

3. Two marbles of equal mass are rolling towards each other. One is rolling at 7 m/sec and the 

            other at 10 m/sec. The one rolling faster has a________ momentum and ________

            impulse. It will surely knock the other one backwards.

• lesser, lesser         

• lesser, greater       

• greater, lesser     

• greater, greater

4. Two identical cars are travelling along the freeway, one car is traveling faster. Which of the two cars would have a greater momentum?

• Both have the same momentum

• The faster car

• The slower car

• Cannot be determined

5. Michael is driving his car at a very low speed. A certain amount of force must be applied to stop his car. Which condition below guarantees the need for a higher amount of stopping force?

• 
  If the car has more mass.

• 
  If the car has lesser momentum.

• If the car has a lesser velocity.

• If the car has constant momentum.
