The displacement x of a simple harmonic motion is given by X = 24 cos (6.28t + 1.57) meters. What is the maximum speed of the oscillator.

And for this case we can write this expression like this:

The velocity would be given by the first derivate and we got:

And the maximum velocity would be:

Explanation:

For this case we have the following function for the position:

And for this case we can write this expression like this:

The velocity would be given by the first derivate and we got:

And the maximum velocity would be:

0.11 m/s and 0.28 m/s should be correct

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
