You and a friend are taking a walk on a cliff with the ocean 20 m away from the bottom of the cliff. You regularly play baseball and know that the furthest you can throw a ball is 10 m. You throw a baseball -sized rock with all your might and it barely makes it to the water . You tell your friend that you can figure out the height of the cliff but he doesn t believe you. How could you explain to your friend how to find the height of the cliff?Please give solution methods.

You fire three shots from your gun (lets label the shots A, B, & C). one straight up (A), one straight down (B), and one horizontally (C). Assuming that you shoot from the hip (i. e. your hand is in the same place each time, right by your holster) and you ignore air resistance.
a. Which of the three bullets (A, B, or c ) will have the greatest speed as it reaches the ground?
b. Now include air resistance, how does your answer change and why?
