Projectile Motion: Ball thrown over a house (Physics)!

You're 6.0 m from one wall of a house. You want to toss a ball to your friend who is 6.0 m from the opposite wall. The throw and catch each occur 1.0 m above the ground.

a) What minimum speed will allow the ball to clear the roof?
b) At what angle should you toss the ball?

Hey guys, join me as I go through this projectile motion question step by step to answer the questions above. The question comes from the textbook Physics a Strategic Approach, by Randall D. Knight, Second ed.

Bro why did u make this whole thing that complex. it is a dam easy one with just 2-3 steps

In the step where you calculate Viy, why dont you multiply the ayΔy by 2? The equation is Vf^2 = Vi^2 + 2aΔx so what happened to the 2??

what book was that? can you lease mention its name?

Damn this was on the test. I fucked up on the x initial velocity

Thank you so much! I was stuck on this question for 2 days. My mistake was trying to find the angle and the magnitude at the same time, which made things very confusing.
