2. Y=Yi+Viy(t)-1/2gt^2

3.

Viy=46.1 m/2

Y & Yi=0

Theta Angle=44.1 degree

g=9.8m/s^2

I used this equation: Y=Yi+Viy(t)-1/2gt^2

0=0+46.1cos44.1(t)-1/2gt^2

4.9t^2/4.9t=33.106t/4.9t

t=6.756s

I drew the x/y coordinate system, right angle and sin/cos to help with solving the problem.

The online hw site says my answer is wrong. Please help. What am I doing wrong? Is it the equation or my algebra?
