Determine the stopping distances for a car with an initial speed of 96 and human reaction time of 0.80 , for an acceleration of -3.8m/s^2.
A helicopter is ascending vertically with a speed of 5.31 . At a height of 144 above the Earth, a package is dropped from a window. How much time does it take for the package to reach the ground?
A rock is dropped from a sea cliff, and the sound of it striking the ocean is heard 3.8 later. If the speed of sound is 340 , how high is the cliff?
A stone is thrown vertically upward with a speed of 15.0 from the edge of a cliff 61.8 high. How much later does it reach the bottom of the cliff? What is its speed just before hitting? What total distance did it travel?
