Two people stand across from one another at the top edges of identical buildings, 50 meters above the ground. One person throws a rock straight upwards with an initial speed of 15 m/s, while the other person throws their rock straight downwards with an initial speed of 15 m/s. If both of the rocks miss the building and continue down to the street, a. How long will it take for the rock thrown upwards to reach the ground? b. How long will it take for the rock thrown downwards to reach the ground? c. How fast will the upward thrown rock be travelling just before it hits the ground? The downward thrown rock?
