Part A Drop Tower NASA operates a 2.2-second drop tower at the Glenn Research Center in Cleveland, Ohio. At this facility, experimental packages are dropped from the top of the tower, on the 8th floor of the building. During their 2.2 seconds of free fall, experiments experience a microgravity environment similar to that of a spacecraft in orbit. What is the drop distance of a 2.2-s tower? Express your answer using two significant figures. ΑΣΦ ? Submit Request Answer • Part B How fast are the experiments traveling when they hit the air bags at the bottom of the tower? Express your answer using two significant figures. ? m/s Submit Request Answer • Part C If the experimental package comes to rest over a distance of 0.74 m upon hitting the air bags, what is the average stopping acceleration? Express your answer using two significant figures. aay = m/s Submit Request Answer

1) Two bike-riders, Sarah and Christina leave the park at the same time and ride in different directions. Sarah travels north at a uniform rate that is 4 mph faster than Christina, who is traveling south. After 1.5 hours, they are 300 miles apart. Find Sarah's and Christina's rate. d. Sarah Christina Sarah: Christina 2) The perimeter of a rectangle is 306 inches. The length is 3 inches longer than four times the width. Find the width and length. Width: Length:

Hi thank you for that solution. In an exam would I be given those formulas or do I need to know them for myself?

Hi I am looking for help with problem #4

RunwayContext A small recreational plane needs to reach a certain speed to be able to take off. Your objective is to plan the length of the runway needed so that small planes can have enough space to take off. Constraints The speed at which the plane manages to take off is known;Planes are initially motionless when departing the runway;The acceleration produced by the aircraft engine is known;We will add 100m to the required length for safety reasons and to account for variations caused by wind; Modelization Models the total runway length (including the 100 m safety) as a function of the speed required to take off as well as the acceleration produced by the aircraft engine. Then test your model with the following parameters: take-off speed: 83 km/ℎ; acceleration produced by the motor: 0.97 m/s^2;

Kinematics A stream flows at a rate of 3.9 km/hr. A boat has a speed of 7.6 km/hr. While in the stream the boat travels upstream a distance of 2 km as measured along the shore, then travels back downstream to its starting point. Neglect the time to turn around. a. Find the time it takes the boat to go upstream b. Find the time it takes the boat to do downstream c. What would it have taken to make the entire round trip in still water?

PRINTER VERSION 1 BACK NEXT Chapter 02, Problem 043 Go Z Your answer is partially correct. Try again. When a high-speed passenger train traveling at vp = 152 km/h rounds a bend, the engineer is shocked to see that a locomotive has improperly entered onto the track from a siding and is a distance D = 670 m ahead (see the figure). The locomotive is moving at v = 32 km/h. The engineer of the passenger train immediately applies the brakes. Assume that an x axis extends in the direction of motion. What must be the constant acceleration along that axis if a collision is to be just avoided?

Suppose that you walk 22 blocks north, 16 blocks east, and 26 blocks south and the city blocks all have the same length. a.) How many blocks are you from where you started? b.) In what direction are you from where you started, measured counterclockwise from due east?

a snake crawls from a hole to find food. it starts at 8m southwest; then goes 10m 40 degrees north of west; then sensed something moving 9m south from where it is and moves to it.   a. how far and in what direction was the moving object from the hole? b. if after realizing that the moving object was not good for food, the snake moved from it because it saw another moving thing, moved to its direction by covering a fourth displacement and is now 20m and 30 degrees east of south from the hole. what is the magnitude and direction of the fourth displacement?
