Answer:
a) Time = 2.67 s
b) Height = 35.0 m
Explanation:
a) The time of flight can be found using the following equation:
 (1)
   (1)
Where:
 : is the final position in the horizontal direction = 80 m
: is the final position in the horizontal direction = 80 m
 : is the initial position in the horizontal direction = 0
: is the initial position in the horizontal direction = 0
 : is the initial velocity in the horizontal direction = 30 m/s
: is the initial velocity in the horizontal direction = 30 m/s
a: is the acceleration in the horizontal direction = 0 (the stone is only accelerated by gravity)
t: is the time =?   
By entering the above values into equation (1) and solving for "t", we can find the time of flight of the stone:    

b) The height of the hill is given by:
 
 
Where:
 : is the final position in the vertical direction = 0
: is the final position in the vertical direction = 0
 : is the initial position in the vertical direction =?
: is the initial position in the vertical direction =?
 : is the initial velocity in the vertical direction =0 (the stone is thrown horizontally)
: is the initial velocity in the vertical direction =0 (the stone is thrown horizontally)            
g: is the acceleration due to gravity = 9.81 m/s²
Hence, the height of the hill is:
