ppose you decide to throw down a melon from rest from the first observation platform of the Eihel Tower. The initial height h from which the melon is released is 58.3 m above the head of your French friend Pierre, who is standing on the ground right below you. At the same instant you throw down the melon with speed of 5 m/s, Pierre shoots an arrow straight up 25.1 m/s. (Of course, Pierre makes sure the area around him...

8. Suppose you decide to throw down a melo Eifel Tower. The initial height h from which the melon is released is 58.3 m above the head of your French friend Pierre, who is standing on the ground right below you. At the same instant you thow down the melon with speed of 5 m/s, Pierre shoots an arrow straight up with an initial velocty 25.1 m/s. (Of course, Pierre makes sure the area around him is cleared and gets...

While standing on a bridge 30.0 m above the ground, you drop a stone from rest. When the stone has fallen 5.00 m, you throw a second stone straight down. What initial velocity must you give the second stone if they are both to reach the ground at the same instant? Take the downward direction to be the negative direction.

From the top of a 70 m building, you throw a ball straight up at 6 m/s. The ball misses the building on the way down. What is the maximum height of the ball? What is the velocity of the ball after 2 s? What is the final velocity of the ball (just before it hits the ground) Now, the ball is thrown straight down at 6 m/s. What is the velocity of the ball after 2 s? Using the initial...

1. A locomotive is accelerating at 1.46 m/s2. It passes through a 24.2-m-wide crossing in a time of 2.30 s. After the locomotive leaves the crossing, how much time is required until its speed reaches 29.7 m/s? 2. A ball is thrown straight upward. At 6.60 m above its launch point, the ball’s speed is one-half its launch speed. What maximum height above its launch point does the ball attain? 3.While standing on a bridge 18.9 m above the ground,...
You throw your phone straight out horizontally so that is leaves your hand with a velocity...
You throw your phone straight out horizontally so that is leaves your hand with a velocity of 15.6 m/s forward. When the phone leaves your hand, its vertical height is 1 m above the ground. Once it leaves your hand, it begins to fall while moving forward due to gravity pulling it downward. a. What is the phones initial velocity in the horizontal (forward) direction in the instant it leaves your hand? b. What is the phones initial velocity in...

In order to defeat Bowser, suppose Mario launched a stone from his sling with an initial velocity of 30.5 m/s at an angle θ=20 degrees above the horizontal. The stone flies through the air and strikes Bowser between the eyes exactly 2.00 seconds after it was released. Assume Mario and Bowser are standing on flat ground, and the stone strikes Bowser on its way back down (after reaching its maximum height). You may neglect air resistance. A) how far away...
