Alex climbs to the top of a tall tree while his friend Gary waits on the ground below. Alex throws down a ball with an initial speed of 4.00 m/s from 48.0 m above the ground. The starting height of the ball thrown upward is 1.50 m above the ground. Ignore the effects of air resistance. 1) At what speed must Gary throw a ball up in order for the two balls to cross paths 24.0 m above the ground? (Express your answer to three significant figures.) m/s Submit

Explore A baseball is thrown from the top of a tall building with an initial velocity of 10 m/s from a height of h= 11.5 m above the ground. Find its speed when it reaches the ground (a) if its launch angle is 37°, and (b) if it is launched horizontally. Conceptualize As the baseball moves upward and to the right, the force of gravity accelerates it downward. The vertical component of its velocity decreases in magnitude until the baseball...
