4. A stone is thrown straight down from the observation deck of a tall building 450 meters above the ground at a speed of 5 meters/sec. Assume that the acceleration due to gravity is a constant function -9.8 m2. (1) Find the distance of the stone above the ground at time t, i.e. its position at time t. (2) When does the stone Hit the ground? At what speed does it hit the ground?

In World War II, there were several reported cases of airmen who jumped from their flaming airplanes with no parachute to escape certain death. Some fell about 20,000 feet (6000 m), and some of them survived, with few life-threatening injuries. For these lucky pilots, the tree branches and snow drifts on the ground allowed their deceleration to be relatively small. If we assume that a pilot's speed upon impact was 123 mph (54 m/s), then what was his deceleration? Assume that the trees and snow stopped him over a distance of 3.0 m.
If an object is thrown straight up and air resistance is negligible, then its speed when it returns to the starting point is the same as when it was released. If air resistance were not negligible, how would its speed upon return compare with its initial speed? How would the maximum height to which it rises be affected?
"In 1865, Jules Verne proposed sending men to the Moon by firing a space capsule from a 220-m-long cannon with final speed of 10.97 km/s. What would have been the unrealistically large acceleration experienced by the space travelers during their launch? (A human can stand an acceleration of 15g for a short time.)" Also "Compare your answer with the free-fall acceleration, 9.80 m/s2."

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 7.27m/s. The stone subsequently falls to the ground, which is 13.9 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use epsilon = 9.81 m / s ^ 2 for the acceleration due to gravity What is the impact speed in m/s? How much time is the stone in the air? Elapsed time
To help travelers get around the airport, a shuttle was built between two terminals. Starting from rest, the shuttle accelerates at 0.447 m/s2 for 37.1 s, cruises at this constent velocity for 62.5 s, and then deaccelerates at -0.275 m/s2 until it comes to a stop. What is the distance between the terminals?
