Here we go again (yes, this set of questions is starting to feel like Groundhog Day). You AGAIN wake up in a strange room, and this time you drop a ball from a height of 2.27 m, and observe that it hits the floor 0.204 s after you drop it. In this case you suspect you are in deep space, far from any planet or star, and that your rocket is accelerating due to the push of its own engines under the floor. In this case, what must the acceleration of your rocket be? 81.8 m/s^2 81.8 m/s^2 109.1 m/s^2 54.5 m/s^2

OK, yet another strange awakening in a room with no windows. This time you drop a ball from a height of 2.50 m and it hits the floor 0.214 s after you drop it. This time you suspect you are on a rocket that has just left the surface of the Earth, and is still not too far above the ground. What do you deduce the rocket s acceleration to be? 99.4 m/s^2 119.0 m/s^2 109.2 m/s^2 149.1 m/s^2
An unidentified flying object (UFO) is observed to travel a total distance of 23000 m, starting and ending at rest, over a duration of 2.59 s. Assuming the UFO accelerated at a constant rate to the midpoint of its journey and then decelerated at a constant rate the rest of the way, what was the magnitude of its acceleration? Express your answer in g s , where 1 g = 9.81 m/s^2. 699 g s 13,715 g s 6,857 g s 1,398 g s
A rescue helicopter is hovering over a person whose sailboat has capsized. One of the rescuers tosses a life preserver straight down to the person with an initial speed of 1.25 m/s and observes that it takes 1.75 s to reach the water. How high above the water was the preserver released? Note that the downdraft of the helicopter reduces the effect of air resistance on the falling life preserver, so that an acceleration equal to that due to gravity is reasonable.
You wake up in a strange room, and this time you drop a ball from a height of 1.74 m, and observe that it hits the floor 0.298 s after you drop it. In this case you suspect you are in deep space, far from any planet or star, and that your rocket is accelerating due to the push of its own engines under the floor. In this case, what must the acceleration of your rocket be? 74.5 m/s^2 74.5 m/s^2 19.6 m/s^2 29.4 m/s^2
The first supersonic flight was performed by Charles Yeager in 1947. During his attempt, he flew from 119 m/s to top speed, accelerating at 7.29 m/s^2 for a distance of 5251 m. What top speed did he achieve?
What happens if the person on the cliff throws the rock straight down, instead of straight up? To explore this question,calculate the velocity of the rock when it is 5.10 m below the starting point, and has been thrown downward with an initialspeed of 13.0 m/s.
You are on the roof of the lecture hall, 51.8 m above ground. As your physics professor, who is 1.8 m tall, walks towards the hall at a constant speed of 1.2 m/s. If you wish to drop an egg on your professor's head, where should the professor be when you release the egg? Assume egg is in freefall and air resistance is ignored.
For a water balloon launched from a 4949-meter overlook with an initial vertical velocity of 24.524.5 meters per second, the height hh in meters as a function of time tt in seconds is h=−4.9t2+24.5t+49h=−4.9t2+24.5t+49. When will the balloon land and burst?
The Denver Nuggets Super mascot, Rocky, can fire T-shirts out of a potato cannon at a rate of 65 feet per second. The cannon propels the t shirts from an initial height of 8 feet above the ground. Is it possible for Rocky to fire t shirts to the upper deck of Ball Arena which itself is 70 feet above the ground?
At the beginning of a basketball game, a referee tosses the ball straight up with a speed of 4.6 m/s. A player cannot touch the ball until after it reaches its maximum height and begins to fall down. What is the minimum time that a player must wait before touching the ball? (Cutnell 2.42) 0.47 s
An unidentified flying object (UFO) is observed to travel a total distance of 19000 m, starting and ending at rest, over a duration of 4.23 s. Assuming the UFO accelerated at a constant rate to the midpoint of its journey and then decelerated at a constant rate the rest of the way, what was the magnitude of its acceleration? Express your answer in g s , where 1 g = 9.81 m/s^2.
You wake up in a room with no windows. You drop a ball from a height of 1.79 m and it hits the floor 0.242 s after you drop it. This time you suspect you are on a rocket that has just left the surface of the Earth, and is still not too far above the ground. What do you deduce the rockets acceleration to be? 102.6 m/s^2 51.3 m/s^2 70.9 m/s^2 61.1 m/s^2
