(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) . The following are speeds and headings displayed on a GPS receiver, (Heading gives the direction of motion based on north = 0°, east = 90°, south = 180°, etc,) In each case, indicate whether the receiver was accelerating during the time between the displays and, if it was, describe in what way the receiver was accelerating. (a) Initially: 60 mpht 70°; 5 seconds later: .50 mph, 70°. (b) Initially: .50 mph, 70°; 5 seconds later: 70 mph, 70°. (c) Initially: 60 mph, 70°; 5 seconds later: 60 mph, 90°.
After watching the video of Felix Baumgartner setting the world record free fall, answer these two questions and upload to this folder. For both questions assume he was in free fall with no air resistance. Also assume the acceleration due to gravity is 10 m/s^2. 1. How fast is Felix going after 30 seconds? 2. How far did Felix fall after 30 seconds?
This is one of the twelve images that make up "The Horse in Motion", copyright 1878 by Eadweard Muybridge and now available via Creative Commons license. In this image, the two front legs are rotating in opposite directions from our point of view one clockwise and one counter-clockwise around their respective shoulder joints. These images and those like them helped scientists understand the physics of gross-motor-motion for living things. In your first post, discuss the functional morphology or gait of a person or animal species as it relates to your data and observations. For example: How does a person change the moment of inertia of their arm when beginning to run as compared when they are walking? If you look at a picture of a running horse like the one shown below, can you tell which legs are rotating so that the foot moves toward the front of the horse and which are rotating in the opposite direction? If you watch the movement of a gymnast or diver, find/create a video clip…
Solve and answer the following question showing the complete step-by-step process. 1. A 50.0-g Super Ball traveling at 25.0 m/s bounces off a brick wall and rebounds at 22.0 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.50 m/s, what is the magnitude of the average acceleration of the ball during this time interval?
Provide an explanation outlining the underlying physics principle and using correct terminologies. In answering these problems, apply appropriate formulae, principles, and equations What is the instantaneous velocity of a freely falling object 10 seconds after it is released from a position of rest? What is the average velocity during this 10 second time interval? How far will it fall during this time?

The graph above represents the data from Activity 3 in this week's lab describing the position of a moving cart as a function of time. The equation for the best-fit line for this position vs. time graph is y = 3.9609x + 0.1739. What distance would you expect the cart to travel if you let it move for 53 seconds?
Solve this problem using Jupyter Notebook 2. Use of SciPy must be demonstrated in your solution3. Use of latex to format numbers, variables and equations4. Use of matplotlib for graphingA ball is thrown vertically upward from the ground with an initial velocity of 39.2 m/sec. If the only force considered is that attributed to the acceleration due to gravity, find (i) how long will it take for the ball to strike the ground? (ii) the speed with which will it strike the ground? and (iii) how high the ball will rise?Read more on Sarthaks.com -
