OK, this is the last time for one of these crazy adventures. THIS time, though, there is a window in the floor, and you can see that you re in a rocket which has just taken off from the surface of an alien planet. By taking careful measurements out that window you determine that the rocket is accelerating upward at 8.00 m/s^2. When you drop a ball from a height of 2.41 m, it hits the floor 0.209 s later. What is the value of g for the alien world below you? a. 111.3 m/s^2 b. 153.5 m/s^2 c. 102.3 m/s^2 d. 120.2 m/s^2

Planet X was just discovered orbitinga nearby star! It orbits a start that is 6.9 times themass of our sun in a solar system just 31.3 light-years away. The acceleration due to gravity thereis 0.07 g. After making some measurements in lab, you start to daydream about travel to other planets. Your spring gun can launch a projectile with a speed of 3.7 m/s. What would happen if you were tolaunch a projectile at an angle of 32 ° abovehorizontal on Planet X? (a) What maximum height would the projectilereach?(b) How far would the projectile travel before ithit the ground? Assume the projectile lands at the same height it was launched from.
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
A spaceship ferrying workers to Moon Base I takes a straight-line path from the earth to the moon, a distance of 384,000km. Suppose the spaceship starts from rest and accelerates at 20.0 m/s^2 for the first 15.0 min of the trip, and then travels at constant speeduntil the last 15.0 min, when it slows down at a rate of 20.0 m/s^2 , just coming to rest as it reaches the moon. (a) What fraction of the total distance is traveled at constant speed? (b) What total time is required for the trip?
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 2.16 m, and observe that it hits the floor 0.199 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? 54.5 m/s^2 54.5 m/s^2 174.6 m/s^2 109.1 m/s^2
I need help with this question? G= 10m/s^2 An object is released from rest by someone standing on a bridge. The object falls without hitting anything for 2.1 s. How fast will the object be going at the end of that 2.1s interval?
Standing from the top of the building and I want to hit the root of the big tree below. The height of the building is 90m and the tree is 60m away from the foot of the building. If a throw a stone with a speed of 18 m/s, will I hit the target? If yes explain it. If no at what distance will I miss the target?
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 2.10 m, and observe that it hits the floor 0.393 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? Question 3 options: 13.6 m/s^2 20.4 m/s^2 46.2 m/s^2 27.2 m/s^2
Christopher watches a stick float downstream in a river and notices that it moves 15 m [El in a time of 2.5 x 10' s. His friend, John, is starting on the south side of the river and is going to swim across. In still water, John knows that he can swim with a speed of 1.2 m/s, relative to the water. a) What is John's velocity relative to the shore? b) If the river is 1.5 km wide, how long will it take John to cross the river? c) How far downstream will be land?
A spaceship is traveling at a velocity of v0 = (37.3 m/s)i when its rockets fire, giving it an acceleration of a = (2.55 m/s2)i + (4.19 m/s2)k. How fast, in m/s, is the rocket moving 6.06 s after the rockets fire?
You encounter a moving walkway that is 81 m long and has a speed of 2.1 m/s relative to the ground. How long would it take you to cover the 81 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.6 m/s relative to the walkway? Express your answer using one significant figure.
