You are woken up in the morning on the farm by a rooster. The rooster is located 30 meters away on top of the 5 meter barn house. If you throw your alarm clock at an angle of 53 degrees at the rooster, so that it hits the rooster on the way up, with what velocity do you need to throw your alarm clock

Complete Question

The complete question is shown on the first uploaded image

The velocity is  

Explanation:

From the question we are told  that

     The distance of the rooster from farm house is  

       The height of the rooster from the ground is  

       The angle at which the alarm clock is thrown is

Let the velocity at which the alarm clock is thrown be  v

  So the horizontal component  of v is mathematically represented  as  

The distance covered by the alarm clock toward the horizontal direction at velocity v is

=>    

=>      

substituting for  

=>      

Considering the motion of the alarm clock in the vertical direction

       So the vertical component  of v is mathematically represented  as

The distance covered in the vertical direction is mathematically evaluated  as follows

From the equation of motion we have

Recall  

So  

 substituting for  

=>  

Now  

So

=>  

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

b would be the answer
