1. A hard-boiled egg is thrown HORIZONTALLY off a180 meterhigh building. The building is located somewhere on the surface of Earth. 300 horizontal meters away from the edge of the building, the egg lands on the ground. The Question: What was the egg's initial (horizontal) speed (10 pts)? 2. Near the surface of Earth, a helicopter travels upward. At some moment, t = 0, the instantaneous upward velocity is v, = 30 m/s. At all moments, the acceleration points downward and is constant in magnitude, a = 5 m/s'. At t = 0, a package drops out of the helicopter. The package is neither thrust nor shoved; it is merely released. The helicopter continues to move up at the same constant velocity. The Question: After 3 seconds have elapsed ('om t = 0), by how many meters are the helicopter and package separated ( 10 pts)? 3. At t = 0, a street hockey stick slaps a puck, giving the puck an unknown initial horizontal velocity, v\". The street surface underneath the puck is rough, so the hockey puck loses speed at every instant of its motion -- from the very rst to the very last. The puck slows down at a constant rate: Every second, the puck loses the same amount of speed. From t = 0, the puck takes 15 seconds to come fully to rest. During this time, the puck travels 225 meters. Let the the direction of puck's motion be designated '+', so na > 0. The Question: How far does the puck travel in the FIRST SECOND of its journey (10 pts)
