About the Lecture
The lecture Momentum: Derived Quantities by Jared Rovny, PhD is from the course Momentum.
Included Quiz Questions
An object bounces off a wall, changing its momentum from +5 kg∙m/s to -2 kg∙m/s. What is the impulse of the collision?
- -7 kg∙m/s
- +7 kg∙m/s
- -3 kg∙m/s
- +3 kg∙m/s
- It depends on the time of the collision.
During a 0.2 second collision, an object experiences an impulse of 10 kg∙m/s. What was the average force on the object during the collision?
- 50 N
- 5 N
- Not enough information
- 20 N
- 2 N
An object initially has a momentum of +5 kg∙m/s. A force of 5 N is applied to the object for 2 seconds in its direction of motion. What is its final momentum?
- 15 kg∙m/s
- 10 kg∙m/s
- 20 kg∙m/s
- 5 kg∙m/s
- -5 kg∙m/s
