Projectiles: A projectile is fired from point 0 at the edge of a cliff, with initial velocity components of \( v_{0 x}=60.0 \mathrm{~m} / \mathrm{s} \) and \( v_{0 y}=145 \mathrm{~m} / \mathrm{s} \), as shown in the figure. The projectile rises and then falls into the sea at point \( P \). The time of flight of the projectile is \( 40.0 \mathrm{~s} \), and it experiences no appreciable air resistance in flight. What is the magnitude of the velocity of the projectile \( 22.0 \mathrm{~s} \) after it is fired?
