Determine the resultant velocity in the following case: A boat's engine can give it a velocity of 25m/s. If the boat heads due east across a river which is flowing due south with a velocity of 8.5m/s; what is the resultant velocity of the boat? (Remember you must find both a magnitude and a direction.)

Steelhead trout migrate up stream to spawn.occasionally they need to leap up small waterfalls to continue their journey. fortunately, steelhead are remarkable jumpers, capable of leaving the water at a speed of 8.0 m/s. a. what is the maximum height a steelhead trout can jump? b.leaving the water at 8.0 m/s, the trout lands on top of the water fall 1.8 m high. how long was it in the air?
