# Question #b5dd9

##### 2 Answers

Suppose that the ball was thrown at

Now, considering vertical motion,it has to reach

So, we can use,

Where,

So,

Or,

The initial velocity is

#### Explanation:

Let 's have a rectangular coordinate system

Then the coordinates of the hoop are

Let the initial velocity of the ball is

The vertical component of the ball is

And

The horizontal component is

Substituting this value of

Let the acceleration due to gravity be

Plugging in the coordinates of the hoop

Solving for

graph{(y-0.839x+0.0735x^2)(y-1.05)=0 [1.31, 21.31, -1.11, 8.89]}
