A person sticks their arm out over a 32 m tall building and throws a 260 gram brick straight upward, then pulls their arm in so that the brick doesn't strike their arm when the brick falls back down. The speed of the brick is 29 m/s at the instant just before the brick touches the ground at the base of the building.
What is the initial speed the brick had at the instant it was
being thrown upward?
| greater than 20 m/s |
| between 18 and 20 m/s |
| between 16 and 18 m/s |
| between 14 and 16 m/s |
| less than 12 m/s |
| between 12 and 14 m/s |
