The crankshaft of an engine increases its spin from 1,000 to 2,000 rpm in 0.50 s what is its angular acceleration

angular acceleration = 209.44 [rad/s^2]

Explanation:

First we have to convert the velocities which are in revolutions per minute to radians on second.

where:

Now we can find the angular acceleration:

a.) is the correct answer.

explanation:

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
