Document Summary
A particle moving along a curve other than a straight line is in curvilinear motion. The position vector of a particle at time t is defined by a vector between origin o of a fixed reference frame and the position occupied by particle. P defined by at time t and p" defined by at t + t, A projectile is fired from the edge of a 150m cliff with an initial velocity of 180 m/s at an angle of 30 with the horizontal. Neglecting air resistance, find: (a) the horizontal distance from the gun to the point where the projectile strikes the ground (b) the greatest elevation above the ground reached by the projectile. Consider the vertical and horizontal motion separately (they are independent) Determine time t for projectile to hit the ground, use this to find the horizontal distance.
