How did everyone find it? I think it was ludicrously difficult. Couldn’t really do any of them. I was thinking if we can kinda check our answers here so we can know if we got any of them right. Ideas? For example I got 5/4 for the tan beta one and 1.56m for the distance travelled by A for the last one.

isn't it obvious that the answer would be in u and G bc the whole question was done in that format?

idk when i substituted the stuff i got s=0
one equation was s=gt²/2
the other was s=ut/2 -gt²/2

you equate both to get the time where they collide and then substitute into the equations and u get u²/8g
