Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following best defines momentum?
The rate of change of velocity.
The product of mass and acceleration.
The product of mass and velocity.
The force applied over a distance.
2. Impulse is equal to the change in an object's:
Kinetic energy.
Potential energy.
Velocity.
Momentum.
3. The principle of conservation of momentum states that in a closed system, the total momentum before a collision is equal to the total momentum the collision.
4. Impulse is calculated by multiplying the average force applied by the over which the force acts.
5. A 2.0 kg bowling ball is traveling at 10 m/s. Calculate its momentum.
6. A force of 50 N is applied to an object for 0.5 seconds. What is the impulse experienced by the object?
7. Momentum is a scalar quantity.
True
False
8. An elastic collision is one in which kinetic energy is conserved.
True
False
9. A 0.15 kg baseball is thrown with a velocity of 40 m/s. It is then hit by a bat, reversing its direction and increasing its speed to 60 m/s. Calculate the impulse imparted to the baseball by the bat.
10. In a head-on collision, a 2000 kg car traveling at 20 m/s collides with a 1000 kg car traveling at 30 m/s in the opposite direction. If the cars stick together after the collision, what is their final velocity?
