1. The problem statement, all variables and given/known data
A projectile is fired at an angle of 30 degrees above the horizontal with a velocity V0 of 460 m/s. Determine the radius of the curvature of the trajectory at the position of the particle 10 seconds after firing.
2. Relevant equations
v = u + at
s = ut + 0.5at(squared)
v(squared) = u (squared) + 2 as
3. The attempt at a solution
No idea. Im trying to do this question but i havent been taught how to work out the angles during flight. Can anyone help?
