Two stones are launched from the top of a tall building. One stone is thrown in a direction 30.0degree above the horizontal with a speed of 10.0m/s ; the other is thrown in a direction 30.0degree below the horizontal with the same speed. Which stone lands farther away from the building?
a. The stone thrown upward lands farther from the building.
b. The stone thrown downward lands farther from the building.
c. Both stones land the same distance from the building.

  1. They both have the same horizontal velocity component, but the ball thrown upward will remain in the air longer.

    So what does that tell you about the disatnce that they travel? Think about it.
