A ruler is initially at rest when a student briefly exerts a
downward force on the right end, as shown. The magnitude of the
force exerted by the student is less than the weight of the ruler.
Assume that the pivot point is frictionless.
Answer the following questions based on this description.
Question 1
While the hand is pushing, but before the ruler begins to move,
the tangential acceleration of the ruler is ______.

John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (see the figure below). The handles make an angle of 0 = 18.0° with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 379 N is exerted at the center of the wheel, which has a radius of 19.0 cm. Assume the brick remains fixed and does not slide along the ground. Also assume the...
