am i the only one that hates physics? ok anyway.

 

please tell me EVERYTHING [basic] you know about projectile motion...

 

Specific question: rock is thrown from the top of a castle wiht initial velocity of 12 m/s [42 degrees above the horizontal.] rock lands on the other side of the river, 9.5m below the initial level. find time of flight, width of river and velocity at impact (resultant velocity)

 

i know its hard to picture. dont tell me the answer..just prompt me...
