During a football game, a player throws the ball east 60 yards. 20 seconds after the ball left his hand a member of the opposing team caught the ball. At what velocity did the ball fly through the air?

Two cars collide, lock bumpers and move together after the collision.this collision is known as perfectly inelastic collision.

Amicroscope, because these cells are so small that you would not be able to see them, or what they attack without 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.
