How Do You Calculate the Entry Velocity of a Ball into a Basketball Hoop?

[Mango12]

I am trying to find the velocity at which a ball enters a basketball hoop. The answer should be -6.42m/s at an angle of -43.6 degrees, but idk how to get that.

The ball starts at a velocity of 7.67m/s and reaches a max height of 4m. The hoop is 3m high, and the ball starts 2.1m above the ground. Can anyone please help.

I tried doing v^2=vo^2+2a(delta x) but I didn't get the right answer...help please!

Hi Mango12,

I noticed you have the [SOLVED] tag in your title, but just to make sure, have you solved this problem entirely? Or did you figure out how to do it?
