P

In this problem, you will practice applying this formula to
several situations involving angular acceleration. In all of
these situations, two objects of masses m₁ and m₂ are
attached to a seesaw. The seesaw is made of a bar that has
length and is pivoted so that it is free to rotate in the vertical
plane without friction.
You are to find the angular acceleration of the seesaw when it
is set in motion from the horizontal position. In all cases,
assume that m₁ > m₂, and that counterclockwise is
considered the positive rotational direction.

This time, the swing bar of mass mbar is pivoted at a different point, as shown in the figure.
(Figure 3)
Find the magnitude of the angular acceleration a of the swing bar. Be sure to use the absolute value function in your answer, since no comparison
of mı, m2, and mbar has been made.
Express your answer in terms of some or all of the quantities mı, m2, mbar, l, as well as the acceleration due to gravity g. Enter the
absolute value function as abs (). For instance, enter abs(x*y) for xy.
