3. In the air track experiment, a glider of mass m1 = 0.150 kg moving with initial speed of 0.571 m/s along the +x-direction collides with another glider of mass m2 = 0.375 kg initial at rest in an elastic collision. Ignoring any frictional forces, what are the final velocities of the two gliders?

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds

Yup no bull frogs here man

The independent variable would be the fertilizer as it is what the dependent variable (the growth of grass) depends on.
