The test starts by throwing a target object from a helicopter at . The test machine fires a projectile from point A B at an angle with the horizontal. The accuracy test is a success and the projectile fired from the machine hits the target object at C . Determine: 40 o θ = a) The initial speed, , with which the projectile was fired from the machine at B v B . b) The trajectory of the projectile (fired from B ). c) The instantaneous radius of curvature, ρ , at 1 t s = (projectile fired from B ). Use the following relationship for the curvature: 3 2 2 2 2 1 dy dx d y dx ρ + = d) The normal and tangential components of the acceleration of the ball at
