A ball is thrown directly upwards with a velocity of 29.0 m/s. What is the maximum height the ball will go ? (Assume g= 9.80m/s2 and no air resistance) h = m. The ball will remain in flight for s. (Use 3 sig figs)

Answerthe valence of an element or radical is equal to the number of positive or negative charges on the ion.

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.
