When an athlete puts a shot, it is 5 / 3M above the ground at the first time of putting the shot. The landing point of the shot is 10m away from the corresponding point on the ground at the first time of putting the shot. The highest point of the shot is 3M above the ground. It is known that the route of the shot is a parabola. The analytical formula of the parabola can't be solved

It is known that the route of the shot is a parabola. The analytical formula of the parabola can't be solved

Let y = a (x-m) 2 + n
Because the highest point is 3M,
So y = a (x-m) 2 + 3
Substituting (0,5 / 3) (10,0) into
m=4 a=-1/12
So y = - 1 / 12 (x-4) 2 + 3
