The rock misses the building on its way down, and is observed to strike the ground 4.00 seconds after being thrown. Neglect any effects of air resistance. With what speed was the rock thrown? A 2.87 m/s B) 7.6 m/s 3.05 m/s D) 12.56 m/s

The polar bear is an excellent swimmer, and it spends a large part of its time in the water. Suppose a polar bear wants to swim from an ice floe to a particular point on the shore. The bear dives into the water and begins swimming. As the bear swims, it tires and slows at a rate of 0.0122 m/s/s. By the time it reaches the shore, which is 40.1 m from where it dove into the water, its velocity is 2.13 m/s. How fast was the bear swimming when it first got into the water? ____________m/s

A California Condor is approaching its nest with a large chunk of carrion in its beak. As it approaches, it makes an upward swoop, achieving a momentary upward velocity of 12.8 m/s when the carrion falls from its mouth, hitting a cliff outcropping 32.1 m below. Determine the speed of the carrion upon hitting the outcropping.
A rock is thrown directly upward from the edge of the roof of a building that is 43.8 meters tall. The rock misses the building on its way down, and is observed to strike the ground 4.00 seconds after being thrown. Take the acceleration due to gravity to have magnitude 9.80 m/s^2 and neglect any effects of air resistance. With what speed was the rock thrown?
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
