Emmy is standing on a
moving sidewalk that moves at +2 m/s. Suddenly, she realizes she
might miss her flight, so begins to speed up, but then she hears
over the PA system that her flight is delayed.
The acceleration
versus time graph shows Emily's acceleration during the 5s time
interval in which all of the events occur. In the velocity versus
time graph, construct a plot of Emmy's velocity over this same time
period.

5 > Attem You are an engineer in charge of designing a new generation of elevators for a prospective upgrade to the Empire State Building. Before the state legislature votes on funding for the project, they would like you to prepare a report on the benefits of upgrading the elevators. One of the numbers that they have requested is the time it will take the elevator to go from the ground floor to the 102nd floor observatory. They are unlikely...

An object with a mass of 5.69 kg undergoes an acceleration of -4.7 m/s^2 for a period of 5.8 seconds. It then undergoes an acceleration of 6.9 m/s^2 for a period of 8.7 seconds. If the initial velocity of the object is 1.51 m/s and it first experiences acceleration when it is at the origin, plot by hand a graph the force, velocity, and position as functions of time. Explain why your graph look the way they do and include...

2. A police car is traveling at a constant velocity of 20.0 m/s due north, when a car zooms by at a constant velocity of 45.0 m/s due north. After a reaction time of 0.800 s the policeman begins to pursue the speeder with an acceleration of 5.00 m/s?. Including the reaction time, how long does it take for the police car to catch up with the speeder? Sketch the position vs time plot for the two motions and show...
