Units
A toy train has a mass of 3.6 kilograms. A child pushes the toy with a constant velocity of 2.0 meters per second. What is the momentum of the train?
What is an 7.2 kg m/s?
This constant is measured in Newtons per Meter and can determine the ability of an object to elongate or be compressed.
What is the spring constant?
Its unit is Hertz
What is Frequency?
A 500-kg satellite at 1 Earth radius away from the surface of the Earth experiences an attractive force of this magnitude by the Earth.
What is 1.56 x 10^4 Newtons?
The wavelength of radio waves in a vacuum with frequency 4.1 x 10^15 Hertz.
What is 7.3 x 10^-8 meter?
A 15. kilogram dog is an expert at catching frisbees. The dog is running at 3 m/s East when it catches a 1.0 kilogram frisbee moving at 5 m/s East. What is the total momentum of the dog/frisbee system?
What is 50 kg m/s?
The time it takes for an emitted sound wave to travel to it's target and return back to the detector if the target is 50 meters away.
What is 0.3 seconds?
How long must a 50 Newton force act on a 10 kilogram object in order to bring it from rest to 2.5 meters per second?
What is 0.5 seconds?
The height of a tower from which a dropped metal ball falls for 3.4 seconds before hitting the ground.
What is 57 meters?
The number of antinodes for a string with fixed ends where a standing wave is shown to have 4 nodes.

A 600. kilogram bumper car moving east at 3 meters per second collides with a 600. kilogram bumper car moving west at 2.0 meters per second in an elastic collision. If they stick together, what is the velocity of the two cars after collision? (Don't forget direction!)
What is 0.5 meters per second East?
8.99 x 10^9 Newton meters squared over Coulombs squared.
What is the electrostatic constant?
The maximum velocity of a 1500.-kg car as it accelerates down a 25 meter long road from an initial speed of 7 meters per second at a rate of 2.0 meters per second squared
What is 12.2 meters per second?
This is the process in which photons oriented in numerous directions travel through a filter/device that makes them travel in only one plane/direction.
What is polarization?
A 600. kilogram bumper car moving east at 3 meters per second collides with a 600. kilogram bumper car moving west at 2.0 meters per second in an elastic collision. If one car moves with a velocity of 1 m/s East after the collision, what is the velocity of the other cart?
What is 0 meters per second?
