Calculate the acceleration of an airplane that starts at rest and reaches a speed of 45 m/s in 9 seconds

Because no mass or force is given for this equation, we'll use a simplified formula for acceleration:

v1 is the initial velocity. v2 is the final velocity. t is the amount of seconds that elapse.

The airplane starts at rest, or at 0 m/s. In 9 seconds, the airplane reaches a speed of 45 m/s. Plug these values into the formula:

The airplane's acceleration is 5 meters per second squared.

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

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
