Chapter 2, Problem 70P
(III) A toy rocket moving vertically upward passes by a 2.0-m-hihg window whose sill is 8.0m above the ground. The rocket takes 0.15 s to travel the 2.0 m height of the window. What was the launch speed of the rocket, and how high will it go? Assume the propellant is burned very quickly at blastoff.

(a) A soccer player kicks a rock horizontally off a 39 m high cliff into a pool of water. If the player hears the sound of the splash 3.02 s later, what was the initial speed
given to the rock (in m/s)? Assume the speed of sound in air is 343 m/s.
m/s
(b) What If? If the temperature near the cliff suddenly falls to 0°C, reducing the speed of sound to 331 m/s, what would the initial speed of the rock have to be (in m/s)
for the soccer player to hear the sound of the splash 3.02 s after kicking the rock?
m/s
An airplane flies with a velocity of 55.0 m/s [ 35o N of W] with respect to the air (this is known as air speed). If the velocity of the airplane according to an observer on the ground is 40.0 m/s [53o N of W], what was the wind velocity?
please do not solve in terms of "i" and "j" .
It was a dark and stormy night, when suddenly you saw a flashof lightning. Six and a half seconds later you heard the thunder.Given that the speed of sound in air is about 340 m>s, how faraway was the lightning bolt? (Ignore the travel time for the flashof light.)
