Homework Statement
A projectile of mass 1300kg is launched from the ground (x =0, y =0)
initial velocity components Vx=Vy=108m/s
aerodynamic drag force is of magnitude C(V)^2
where C = 0.6
Homework Equations
Finding the range and angular momentum initial and final
The Attempt at a Solution
1. I found V = 152.74 (*by V= root(Vx^2 + Vy^2)
2. and weight as 12753 kg
3. I tried to find aerodynamic drag force (FD), but I got something like 13997.70 m^2/s^2
(it should be in Newtons right?)
4. I think I'll break FD to x and y components and use them to calculate when it'll reach it's peak (Vy= 0) and based on it I'll use the the t to get the distance...but how to find it?
5. for the angle, can I assume that it was 45 degrees angle?
since Vx=Vy?
6. and I have no idea how to find the angular momentum @.@
Sorry if my working is quiet "useless" cause I'm quiet "blind" at this subject...
Thanks before :D
