A ball is projected vertically upward from the ground with an initial speed of 49 meters per second. Which of the following is closest to the maximum height reached by the ball?

A.

25 m

B.

49 m

C.

120 m

D.

250 m

The answer is A because if the meters did that and that equals that then the answer of the sun would be A

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.
