Adog sees a flowerpot sail up and then back past a window 5.0 ft high. if the total time the pot is in sight is 1.0 seconds, find the height above the window that the pot rises.

To solve this problem we will use the linear motion kinematic equations for which acceleration (in this case gravity) is described as the change in velocity in an instant of time. Subsequently through the energy conservation equations we will find the net height.

Let's start considering that the time is 1 second, therefore,

Now the acceleration would be given as

Since the final speed is zero, and the time elapsed to reach the height is 0.5 seconds (half of the entire route) we will have that the initial speed can be expressed in terms of gravity as

Now for energy conservation, the potential energy must be equal to the kinetic energy, therefore,

PE = KE

Replacing the previous value found,

Therefore the hegiht above the windows that the pot rises is 1.225m

answer: what are you talking about?

explanation:

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
