maximum possible speed by solving above equation for 7D is
minimum possible value of speed for solving x = 6D is given as
Explanation:
Let the nozzle of the hose be at the origin. Then the nearest part of the rim of the tank is at (, ) = (6, 2) and the furthest part of the rim is at (, ) = (7, 2).
The trajectory of the water can be found as follows:
Now from above two equations we have
now we know that height of the cylinder is 2D so we have
by solving above equation we have
now we know that maximum value of x is 7D
so the maximum possible speed by solving above equation for 7D is
minimum possible value of speed for solving x = 6D is given as
