we should find the time :
19.85*t - 4.33t^2 = 0 , t = 4.58 sec
x=33cos(65-28) *t - .5*g* sin28*t^2 , x=71.75m
To find velocity components:
Vx= 33cos(65-28) - g*sin28*t , Vx= 5.52 m/s
Vy= 33sin(65-28)-g*cos28*t Vy= -19.8 m/s
V=20.56 m/s
To find the direction of V:
tan(a)=-3.59 , (a) = -74.42[/align]

hi my friend ...Obama08
i am anew student in physics .... please can you explain more about this solution and write the equation which you use it tin the solution ... and again thank you.
