Solve the all parts of following question given below:

Question: At the edge of a 12- m-tall building, two children throw rocks at 12 m/ s, one upward and one downward.

Part A: Find the time until the rock, thrown upward, hits the ground.

Part B: Find the time until the rock, thrown downward, hits the ground.

Part C: Find the speed of the rock, thrown upward, when it hits.

Part D: Find the speed of the rock, thrown downward, when it hits.

I need help to determine find the speed of the rock, thrown upward, when it hits. Express your answer to two significant figures.
