Show a step by step process in finding the solution of the problem. If Michael Jordan has a vertical leap of 1.35 m, then what is his takeoff speed and his hang time (total time to move upwards to the peak and then return to the ground)? A kangaroo is capable of jumping to a height of 2.65 m. Determine the takeoff speed of the kangaroo*PLEASE ANSWER #2 and #3* Sketch a graph of how you would expect an instantaneous acceleration vs. time graph to look for a cart released from rest on an inclined track. Next to this graph, sketch a new graph of the acceleration vs. time for a cart with a much larger mass. Explain your reasoning. Write down the equation(s) that best represent each of these graphs. If there are constants in your equation, what kinematic quantities do they represent? How would you determine these constants from your graph? Sketch a graph of instantaneous velocity vs. time for each case. Use the same scale for the time axes as the acceleration graphs. Write down the equation(s) for each graph.

- Eliana likes to use an app to graph her runs. The graph below shows her run from her house to the park and back. a. Write a description of Eliana’s graph. b. What was Eliana’s running speed from her house to the park? Give Units. c. What was Eliana’s running speed 25 minutes after she started her run? How does your answer relate to the slope of the graph? d. What was Eliana’s running speed from the park to her house?1. Using the position-time graph below, calculate the velocity (slope) for each time interval below.Show all your work including directions and units A) Velocity from pointA to B B) Velocity from B to C C) Velocity from C to DPlease helpppp explain I’m confusedddddd For each graph below, try to describe what type of motion (imagine yourself walk- ing along a path in front of a motion detector) would produce such a graph. Con- sider the horizontal axis to represent increments of time and the vertical axis to represent increments of distance from a frame of reference. Then write a detailed description of how you produced the graph. The description should be detailed enough that another group could follow your directions to reproduce the graph and should include such vocabulary as faster or slower rate, increasing function values, decreasing function values, and the function is constant on defined intervals Warning! Some of these graphs may not be functions, and thus do not make sense in a physical way related to motion.
- i need a step by step detail on how to get part b* thank you so much! b) calculate thw magnitude (in km/h) and direction (in degrees north of east) of the hikers average velocity during the given time.Using what's given below, answer the following parts for practice: Ansdrew needs to get produce from the store, which is a distance d=2.87 km east of his condo. Andrew rides his bicycle to the store at a constant speed of v1= 6.19 m/s, and rides back to his condoat the slower speed of v2=2.22 m/s. The figure below is not drawn to scale. Part A: How long, in seconds, does it take for Andrew to reach the store? And how long in both seconds and minutes does the whole trip take? Part B: What total distance, in kilometers, was traveled by Andrew during the whole trip? Part C: What is the magnitude, in kilometers, of Andrew's displacement for the entire trip and what was the direction of his displacement for the entire trip?REQUIREMENTS: take a picture of your work and use the right formula, must be organized and legiable show proper steps/calculations.
