Transcribed Image Text:
At t = 0, a street hockey stick slaps a puck, giving the puck an unknown initial horizontal velocity, vo. The street surface underneath the puck is rough, so the hockey puck loses speed at every instant of its motion -- from the very first 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 12 seconds to come fully to rest. During this time, the puck travels 144 meters. Let the the direction of puck's motion be designated '+', so v > 0. The Question: What are the magnitude and direction of V, the instantaneous velocity of this puck at t = 1 sec At t = 0, a street hockey stick slaps a puck, giving the puck an unknown initial horizontal velocity, vo.
