Question

A juggler throws a bowling pin into the air with an initial velocity vi. Another juggler drops a pin at the same instant. Compare the accelerations of the two pins while they are in the air.

Answer 1

They are the same

Step-by-step explanation:

Neglect air resistance. Both pins are subjected to the same constant gravitational acceleration g = 9.81 m/s2 no matter where they are on Earth. So it doesn't matter what their initial velocities are. Their acceleration would always be the same.
