Find the slope of the graph and compare it with the calculated acceleration.On the velocity-time graph below, sketch a plot representing the motion of an object which is ... . Label each line with the corresponding letter (e.g., "a", "b", "c", etc.) at rest moving in the positive direction at constant speed moving in the negative direction from slow to fast moving in the negative direction from fast to slow moving with a positive velocity and a positive acceleration moving with a positive velocity and a negative acceleration moving with a positive velocity at constant speed and then decelerating to a rest position moving in the positive direction while slowing down, changing directions and moving in the negative directions while speeding upa.) Draw the distance vs. time graph. Find the slope. b.) Describe the graph line. What does it imply? a.) Draw the speed vs. time graph. Find the slope. Describe the graph line. What does it imply? b.) Find the slope of the graph and compare it with the calculated acceleration. Describe the motion of a freely falling body based on the results obtained. If, by some suitable mechanism, the falling body had been given an initial downward push instead of being just released, would the resulting value of `g’ have been different? Explain. Problems: An object is dropped from rest at a height of 300 m.a. Find the velocity after 2 seconds.b. Find the time it takes for the object to reach the ground. c. With what velocity does it hit the ground? A car starting from rest is accelerated 15 m/s2. In how many seconds will its velocity be equal to 100 m/s? How far will it have traveled during this same time?
- A car is moving forward when the brakes are applied, sketch the d vs t graph of this motion, show some tangent lines on your graph showing fast, slower and stoppedA basketball dropped from the roof of a three-story building falls to the ground. Ignoring air resistance, sketch the motion diagram for this motion, including approximate representations of the position versus time, velocity versus time, and acceleration versus time graphs for this motion. Include axes labels, appropriate numbers, and units for each graph. Upload an image of the sketches and explain your sketches in words in the panels below.sketch what you think the speed time graph would look like for a vehicle that begins at 10 m/hr. and remains at that speed for 10 minutes. Label this section A. Then the vehicle (over a five-minute interval) increases speed from 10 to 20 m/hr. Label this section B. Then immediately the vehicle begins to slow down. It takes the vehicle 10 minutes to slow down from 20 m/hr. to zero. Label this section C. This graph would have 3 intervals. The first interval (A) is from 0 to 10 minutes. The second interval (B) is from 10 minutes to 15 minutes. The third interval (C) is from 15 minutes to 25 minutes. The x-axis needs to go from zero to 25 minutes. The y axis needs to go from zero to 20 m/hr. Describe the motion of the vehicle in each interval as increasing, decreasing, constant, or at rest.

What is the object's deceleration in the D-E path?Below is a velocity-versus-time graph for an object. Which is a correct description of the object's motion? The object is moving at a constant velocity. Then it slows down and stops. JO The object rolls along a flat surface. It then rolls down a hill, and finally stops. The object moves along a flat surface. Then it rolls down a hill, and keeps going. The object does not move at first. Then it rolls down a hill, and keeps going. The object does not move at first. Then it moves at a constant velocity, and stops.
