Hi i need answer for number 3. if gravity is needed in the solution, please use 9.81m/s2

3. From the top of the hill inclined at an angle of 30°, a projectile is fired with a velocity of 540 ft /s. If the projectile is positioned perpendicular to the surface of the hill, determine the range down the hill. 4. A sandbag is dropped from a balloon which is ascending vertically at a constant speed of 6 m/s. If the bag is released with the same upward speed of 6 m/s when t =0 and it hits the ground t = 8 s, determine the speed of the bad as it hits the ground and the altitude of the balloon at this instant.
