The launching velocity of a missile is 20.0 m/s, and it is shot at 53º above the horizontal. which of the velocity components (neglecting air resistance) determines the projectile's time in the air?

vertical component ie [email protected] determine time of flight

hope u get it..

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
