- 3. A ball is dropped from the top of a tower of height 100 m. How long will it take to land on the ground? (g = 9.81 ms-2)can you please ans (d) (e) (f)?The question answered is not what I submitted. This is what I submitted An inflatable life raft is released from an airplane at 300 m altitude, in level flight, with an air speed of 120 m/s in the horizontal direction. Neglecting air resistance, how long before the raft strikes the water?
