. At time t = 0, a bullet is fired vertically upwards with a speed of 100 ms–1


At time t = 0, a bullet is fired vertically upwards with a speed of 100 ms–1. A second bullet is fired vertically upwards from the same point and with the same speed at t = 5s. Then,

            (a) The two bullets will be at the same height above the ground at t = 12.5 s          

            (b) The two bullets will reach back their starting point at t = 25s     

            (c) The two bullets will have the same speed at t = 20 s                   

            (d) The maximum height attained by either bullet will be 980 m.
