3. A car traveling at a constant 39 m/s (-87 mph) passes a police car that is initially traveling at 25 m/s (55 mph). At the instant of the pass, the police car accelerates at a constant rate of 3.3 m/s in pursuit. We wish to find how much time elapses before the officer catches the car. (a) Identify the initial states when the car passes the police. (b) Define the final state or conditions which enable...

A car, traveling due north, has an initial velocity of 18 m/s accelerates for 9 s for a distance of 180 m. What is the velocity of the car after the acceleration? (5) A remote controlled car is moving through a parking lot described by the position function r(t) = [2.5 m - (0.015 m/s^2) t^2] i - [0.6 m - (0.1 m/s) t + (0.032 m/s2) t^2] j. What is the speed of the toy car at t =...

The plot below displays the velocity as a function of time for
two physics students, Alan and Betty, for 10 seconds after a
stopwatch is started at time t = 0. Alan and Betty are both
initially standing at the same position, defined as
x = 0, and subsequently move along a straight line that we
define as our x-axis. The plot for Betty’s velocity as a function
of time vB(t) is itself a straight line while the plot for...

The plot below displays the velocity as a function of time for two physics students, Alan and Betty, for 10 seconds after a stopwatch is started at time0. Alan and Betty are both initially standing at the same position, defined as x -0, and subsequently move along a straight line that we define as our x-axis. The plot for Betty's velocity as a function of time vs() is itself a straight line while the plot for Alan is a quadratic...

A car is traveling along a straight road at a velocity of +28.1 m/s when its engine cuts out. For the next 2.97 seconds, the car slows down, and its average acceleration is . For the next 4.30 seconds, the car slows down further, and its average acceleration is . The velocity of the car at the end of the 7.27-second period is +21.3 m/s. The ratio of the average acceleration values is = 1.37. Find the velocity of the...
