- An object moves in one dimension, according to the position versus time graph. Express your answers in m/s. A. What is the average velocity between the times 0 s and 0.4 s? B. What is the average velocity between the times 0.4 s and 1 s? C. What is the average velocity between the times 0.6 s and 1.6 s? D. What is the average velocity between the times 0 s and 2 s?Hi I am in phyiscs I and it has the problem a runner ran the marathon (approx. 26.1) in 2 hours and 57 min. What was the average speed of the runner in m/s? I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please detalied steps of how to solve this so I can understand it. Thank you!Plssss help, ignore the writing, Sketch a possible position vs. time graph showing the same motion. Explain why your graph is only one of many possible graphs.
- 1. 1. Draw a graph of velocity as a function of time2. Determine the following from your graph:(a) The change in velocity per unit change in time (i.e. acceleration of the ball). Illustrate onyour graph and show the calculation below. (b) The velocity at t = 0.84 s (interpolation). Illustrate on your graph and write the value below.(c) The velocity at t = 1.74 s (extrapolation). Illustrate on your graph and write the value below.(d) Set up an empirical equation for the velocity of the ball at different times. This equationshould use the numerical values of the constants and indicate their units.Part 1: A motorist traveling at 17 m per s encounters a deer in the road 48 m ahead. If the maximum acceleration the vehicle's brakes are capable of is -5 m per s2 what is the maximum reaction time of the motorist that will allow her or him to avoid hitting the deer? Answer in units of s. Part 2: If his or her reaction time is 1.29353s, how fast will (s) he be traveling when(s)he reaches the deer? Answer in units of m per s.Hi I am in phyiscs I and it has the problem a runner ran the marathon (approx. 26.1) in 2 hours and 57 min. What was the average speed of the runner in m/s? I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please break it down so I can understand. I tried to solve it how you guys did it but I keep getting another answer. Thank you!
- I don't understand how to do this. Now let's see what we can tell from an equation for position:x(t) = 6t^2 + 4.2t + 9What is the object's initial position? Assume each term has units of meters, and that time is in secondsAn object is moving in the air (defying gravity) so that its height after t seconds is given by ℎ(t)=18sin(t)cos(t)+8t meters. (If you graph this function, you can see it's moving up and down, but going higher and higher as time goes on.) a) At what time, t, does the object first change direction from going up to going down? b) What is the acceleration (m/s^2) of the object at that same time?The figure to the right is the position-versus-time graph of a jogger. a) What is the jogger’s velocity at t = 10 s, at t = 25 s, and at t = 35 s? b) Find his average speed between 10 s and 35 s. c) what is the jogger’s average velocity and average speed for the overall trip (0 s to 40 s)? (d) Draw the velocity vs time graph of this motion
- Imagine that you took a road trip. Based on the information in the table, what was the average speed of your car? Time Mile marker 3:00 pm 32 8:00 pm 166 Express your answer to three significant figures and include the appropriate units. Use mimi as an abbreviation for miles, and hh for hours, or mphmph can be used to indicate miles per hour.Based on a grade 11 physics student, answer the following question: The position-time graph below represents the motion of two speed skaters, Bill and Ted on their Excellent Adventure as they time travel back to the 1952 winter Olympics in Oslo. a) What was Ted’s velocity at 20s? b) What was Bill’s velocity during the middle portion of the race? c) What was Ted’s average velocity throughout the race? d) What was Ted’s acceleration through the race? (assume constant) e) Make a velocity-time graph of Bill & Ted’s Speed Skating race.Use the position vs. time graph shown in figure to the right to answer the following questions. On the plot, the x-intervals are Δx = 9 m and the time intervals are Δt = 17 s. A: What is the velocity of segment 1? B: What is the velocity of segment 2? c: What is the velocity of segment 3? D: What is the velocity of segment 4?
