A student throws a 2.5kg ball horizontally off the top of a building with an initial speed of 4.25 m/s. At the same time, another student throws a 1.12kg ball along the same trajectory with the same initial speed. Which of the balls hits the ground first? a. The 2.5kg ball. b. They hit at the same time.     c. The 1.12kgball.

4. A ball is thrown from a point O, which is 6 m above horizontal from ground. The ball is projected with speed u m s' at an angle 0 above the horizontal. There is a thin vertical post which is 4 m high and 8 m horizontally away from the vertical through O, as shown in the figure below. The ball passes just above the top of the post 2 s after projection.
