For number 11(please see the attachment), I keep messing up and I don't know what I'm doing wrong.
To find the answer I know I have to do this:
Speed = sqrt(Vxsquared + Vysquared)
I know that velocity of x is going to stay constant, so its v is 25.5
And for the velocity of y I did this(Vy=Vo*sin(ang)-gt):
Vy= 25.5*sin(29.1)-9.8(4.41) (time is right)
Vy= -30.82
so after plugging these values into the speed equation, I got this answer: 40.
What's wrong with this?
