For Questions 1 through 3, interpret the position graph given in each

figure by writing a very short “story” of what is happening. Be creative!

Have characters and situations! Simply saying that “a car moves

100 meters to the right” doesn’t qualify as a story. Your stories should

make specific reference to information you obtain from the graph, such

as distance moved or time elapsed.

Short Answer

Expert verified

A position-time graph is given here according to which a body is moving with uniform speed and acceleration.

Step by step solution

01

Given data

A position-time graph is given in this question.

02

Story creation

Tiya has gone to her friend's home which is at a distance of 5mifrom her home. She moved to the market from there which is at a distance of 5mifrom her friend's home that took 20min. After another 20minof marketing, she moved back home. Tiya covered a total distance of 10mito her home in localid="1647936182272" 40minuteswith constant speed while travelling back.

Graphical representation

The position-time graph should be as follows:

The takeoff speed for an Airbus A320 jetliner is 80 m/s. Velocity

data measured during takeoff are as shown.

a. Is the jetliner’s acceleration constant during takeoff?

Explain.

b. At what time do the wheels leave the ground?

c. For safety reasons, in case of an aborted takeoff, the runway must be three times the takeoff distance. Can an A320 take off safely on a 2.5-mi-long runway?

The minimum stopping distance for a car traveling at a speed

of 30 m/s is 60 m, including the distance traveled during the

driver’s reaction time of 0.50 s. What is the minimum stopping distance for the same car traveling at a speed of 40 m/s?

Larry leaves home at 9:05 and runs at a constant speed to the lamp post seen in FIGURE EX2.3. He reaches the lamppost at 9:07, immediately turns, and runs to the tree. Larry arrives at the tree at 9:10. a. What is Larry’s average velocity, in m/min, during each of these two intervals? b. What is Larry’s average velocity for the entire run?

Particles A, B, and C move along the x-axis. Particle C has an initial velocity of 10 m/s. In FIGURE P2.37, the graph for A is a position-versus-time graph; the graph for B is a velocity-versus time graph; the graph for C is an acceleration-versus-time graph. Find each particle’s velocity at t = 7.0 s.

FIGURE Q2.5 shows a position-versus-time graph for the motion of

objects A and B as they move along the same axis.

a. At the instant t = 1 s, is the speed of A greater than, less than,

or equal to the speed of B? Explain.

b. Do objects A and B ever have the same speed? If so, at what

time or times? Explain.
