Help! Projectile Motion

[t[-_-]t]

Two stones are thrown simultaneously in line and horizontally from the top of a cliff 78.4m high with speeds 5.00m/s-1 and 20.0m/s-1 respectively. How far apart will they strike the water? Find the velocity of the first stone as it reaches the water. Please explain too, appreciate it

attachment 1: finding how far apart they strike the water
attachment 2: velocity of first stone

hopefully I've done them correctly, it's very possible that I've made some silly error/s

Thank you.

My pleasure, honestly.

Sorry for the hijack.

Fletch-J, what program did you just used just above ^?

I think it would great to interpret the worded problems from maths and physics into diagrams (or depictions). Especially for physics of course!

It's just Microsoft OneNote.. The thing is, my laptop is a touchscreen convertible tablet, so I can write on the screen.
I'm pretty sure you can buy external tablets that can be used with any computer (like this).

Do you mean my laptop? It's a Toshiba Portege M780, but I wouldn't recommend it. I would choose a Lenovo ThinkPad convertible Tablet.
