Chef Susan tosses some pizza dough in the air, then catches it again at the same height. The pizza dough is in the air for . We can ignore air resistance.

What was the dough's velocity at the moment it was tossed into the air?

Answer using a coordinate system where upward is positive.

Round the answer to two significant digits.

Answer:

Let's list all the variables. Remember, upward is the positive direction.

A= -9.81m/s^2

T= 1s

Displacement= 0m

Vf= ?

Vo= ?

How do I know that the displacement equals to 0, when displacement is not given?

In this scenario, the displacement of the pizza dough is indeed 0 meters.

Displacement refers to the change in position of an object.
Since Chef Susan throws the dough upwards and catches it at the same height, the dough doesn't experience any net change in position. It starts and ends at the same point.

Displacement = xi - x0 where xi is the pizza landing back on chefs hand and x0 is the pizza leaving the hand when it is being tossed. So the location on the pizza starts and ends at the exact same point so Displacement = 0
