well, for a) i found t by using t=d/v and got 5.13E-10 s. i found theta by arctan Ay/Ax and i got 27.9 degrees. so then i used yf=yi+(V_yi)t-.5(9.80)t^2 to find the yf and i got 4.67E-3 and it was wrong.
for b)i found the velocity unit vectors and i got it wrong. i did Vxi= Vi(cos27.9) and...
all right, i got the t and solved c.
however, for a) I am still a bit confused. are they asking for his initial position? becuase if they are wouldn't it be 0 for ihat and .443 jhat? i got the 0 ihat correct, but the.443 was wrong?
