PHYSICS HELP PLEASE !!!!!! easy 10 points !?

a) first find the y-component of his initial velocity by making a triangle with the 60 degrees and the 8 as the hypotenuse. this is 8sin60. then use the equation d=Vi(t)+a(t)^2 we have everything but d so solve for d. then, his initial horizontal speed is 8cos60 and does not change so just do d=st
