Kinematics graphs are great for showing how a quantity depends on time. For example, an acceleration-versus-time graph shows how acceleration depends on time. a. Based on your experience with two other kinematics graphs (position- and velocity-versus-time), describe how to plot an acceleration-versus-time graph. b. Describe how all three kinematics graphs are connected by slopes of tangent lines (derivatives). c. If a particles acceleration is positive and constant, what is the shape of the curve in each of the three kinematics graphs?
Please answer the 3 unanswered questions. One is for velocity time graph, while other 2 are foracceleration time graph.
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. What was Ted’s velocity at 20s? What was Bill’s velocity during the middle portion of the race? What was Ted’s average velocity throughout the race? What was Ted’s acceleration through the race? (assume constant) Make a velocity-time graph of Bill & Ted’s Speed Skating race.
Illustrate and solve the following problems following the GRESA format (Given, Required, Equation, Solution, Answer).Express your answer in two decimal places What is the final velocity of the car, if it starts from rest and travelled a 75.0 km distance with an acceleration of 17 m/s2?
What is the meaning of the gradient of distance time graph ? what is the equation of velocity ? what is the unit and Is it vector or scalar?
George walks to a friend’s house. He walks 750 meters North, then realizes he walked too far. He turns around and walks 250 meters South. The entire walk takes him 13 seconds. What is his velocity in meters per second? Also, is the acceleration due to gravity negative or positive or it depends? I'm really confused. Please help and explain in an easy to understand.
A car traveling at 20 m/s when the driver sees a child standing in the road. He takes 0.80 s to react, then steps on the brakes and slows at 7.0 m/s2. How far does the car go before it stops? Use sketches on velocity vs time and acceleration vs time graphs to make your case.
using the information down below generate graphs of the position-time, velocity-time, and acceleration-time data.
How would you expect a velocity vs. time graph to look for a cart moving with a constant velocity? Make a rough sketch of the graph and explain your reasoning. Write down an equation for the graph. Explain what the symbols in each of the equations mean. What quantities in these equations can you determine from your graph?
Imagine that a sprinter accelerates from rest to a maximum speed of 10.8 m/s in 1.8 seconds. In what time interval will he finish the 100-m race if he keeps his speed constant at 10.8 m/s for the last part of the race? Construct avelocity-time graph and explain how you would use it to answer this question.
What is the main difference in velocity graphs when moving slow vs. moving fast?
George walks to a friend’s house. He walks 750 meters North, then realizes he walked too far. He turns around and walks 250 meters South. The entire walk takes him 13 seconds. What is his speed per second? What is his velocity in meters per second? Please show the formula you use and explain it in an easy to understand way.
