A hill is 500 m high. Supplies are to be sent across the hill using a canon that can hurl packets at a speed of 125 m//s over the hill. The canon is located at a distance of 800m from the foot of hill and can be moved on the ground at ba speed of 2 m//s, so that its distance from the hill can be adjusted. What is the shortest time in which a packet can reach on the ground across the hill? Take g= 10 m//s^(2) .
