Without the effects air resistance, the pilot would have a very different experience. Repeat part a, but now assume the pilot was in freefall for the entire 20,000 ft (6000 m).

I don't understand your answer. so you started answer question b before question a ? also isn't the initial velocity should be V0 = 25 m/s ?

Tarzan grabs a vine hanging vertically from a tall tree when he is running at 9.3 m/s. a. How high (in m) can he swing upward? (Enter your answer with respect to the ground.) (Answer in m) b. Does the length of the vine affect this height? (Yes or No)

A rock is thrown straight downward near the Earth’s surface with initial velocity of 20m/s down.  Assuming it doesn’t reach the ground, after 4 seconds its speed will be about

You have put a sonar device at the top of a frictionless inclined plane, as shown in the diagram below. That device allows you to measure the distance an object is from the device, as well as the speed and the acceleration of that object. If we decide that the origin (h = 0) is at the sonar device, we want to know what the height change is as we slide down the incline. 0 For an angle below the horizontal of 6.46, we see that our object has slid a distance 1.13 m, as measured along the incline itself. Calculate the height change in meters - and report your answer as a negative number. (This value would be useful for calculating the change in gravitational potential energy, as we will do in the lab.) h=o 10% O i 26 QUATU 99+ hp X 55 83°F 3:11 PM 10/16/2022 Ctrl 0

At the Earth's surface, a projectile is launched straight up at a speed of 7.5 km/s. To what height will it rise? Ignore air resistance. 2.87e+06 Your response differs from the correct answer by more than 10%. Double check your calculations. m

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 2.48 m, and observe that it hits the floor 0.284 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?     30.7 m/s^2     30.7 m/s^2     123.0 m/s^2     61.5 m/s^2
