Part A Constan A projectile is fired from point 0 at the edge of a cliff, with initial velocity components of vox 60.0 ms and var 175 m/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 400s, and it experiences no appreciable air resistance in flight. What is the magnitude of the velocity of the projectile 210s nfter it is fired? -D→ A projectile fired from the edge of a cliff.

Please explain to me how to get the answer, thank you

An airplane is heading due south at a speed of 590 km/h. If a wind begins blowing from the southwest at a speed of 60.0 km/h (average).

Thank you!
