- In the javelin throw at a track and field event, the javelin is launched at a speed of 8.2 m/s at an angle of 30° above the horizontal. How far has it traveled horizontally (in meters) after 2.0 seconds?A brick is thrown upward from the top of a building at an angle of 30° to the horizontal and with an initial speed of 13 m/s. If the brick is in flight for 3.1 s, how tall is the building?A projectile is thrown from the top of a cliff with an initial speed of 25 m/s at an angle of 600 up from the horizontal. If the projectile lands 100 m from the base of the cliff how tall is the cliff?
