Aprojectile is fired northward out to the sea from the top of a cliff 264 ft high. assuming that the r-axis is pointing east and y-axis is pointing north. the projectile's initial velocity vector is v(0) experiences in flight an eastward acceleration of 3 ft/s2 due to spin. find the projectile's velocity and position vectors t seconds after the projectile is fired. (0, 92, 14). in addition to a downward gravitational acceleration of -32 ft/s2, it
