A ball is projected upward at time tt = 0.0 s, from a point on a roof 30 m above the ground. The ball rises, then falls and strikes the ground. The initial velocity of the ball is 81.9 m/s. Consider all quantities as positive in the upward direction. At time tt = 8.36 s, the vertical component of the ball's velocity is closest to: A. -342 m/s B.+12 m/s C. zero D. -12 m/s E.+342 m/s
Usain Bolt starts from rest, accelerates to the right or finish line at +3 m/s2 (acceleration vector points toward the right or finish line) for the first 4 seconds, then holds a constant velocity for 5 seconds and finally decelerates at -2 m/s2 (deceleration vector points towards the starting block) until the sprinter's velocity is +3 m/s (velocity vector still points toward the right or finish line), which is the speed he maintains while running in the stadium celebrating his Olympic Gold Medal winning sprint. Sketch the acceleration versus time graph, and from this, the velocity versus time graph to determine the time at which the sprinter has decelerated to +3 m/s. Within the first 4 seconds, at what time is the sprinter's velocity +8.5 m/s (vector pointing towards the right or finish line)?
