a stealth bomber on a training mission drops one of its bombs from a height of 3500m during level flight. The bomb travels a horizontal distance of 1.25 km. What was the plane's horizontal speed? a brick is thrown upward from the top of a building at an angle of 25 degrees to the horizontal and with an initial speed of 15 m/s. it strikes the ground below. if teh brick is in flight for 3.0 s, how tall is the building? i dont know the equation or the answer, can someone provide both for me?
