Usually, Tony travels to Bunbury from Perth city in 2.50 hours. One day he increases his
average speed by 12.0 km/h and takes 22.5 minutes less time to reach Bunbury.
(a) What was his usual average speed? What was the distance travelled?
(b) On the way he stopped at a rail crossing (6.00 m wide) and a train (total length 144m)
decelerating at -0.585 ms2 just entered the crossing with a velocity of 13.7 m s¹. Sketch
a diagram and find the minimum time for the last carriage of the train to clear the
crossing.

Estimate the distance traveled by the vehicle during this 65-second period using the velocities at the
beginning of the time intervals.
We can do this by approximating the area under a curve. But what curve? In this case, imagine that the
velocity of the vehicle is a function of time, v(t). We do not have this function, but we do have the values
of th
function at certain points in time. If we assume the function (the velocity) is constant between
these points in time (which is not actually true), we can get an approximation.
distance traveled -
feet
Give another estimate using the velocities at the end of the time periods.

At the scene of a car accident, the forensic investigator measured the skid marks from one of the vehicles to be 83 m long. He also knows the typical acceleration for a car when you slam on the brakes is - 4m / s * 2 The speed limit for this area is 100 km/hr (about 28 m/s) . Was the car speeding before it hit the brakes?

- A train accelerates uniformly from rest at station A to a maximum speed of 72 km/h. The constant maximum speed is maintained for a period of time and the train then decelerates uniformly until it comes to a stop at station B. The distance between the two railway stations is 22 km and the journey takes 20 minutes. If the magnitude of the acceleration is half that of deceleration, by using the graphical method, determine the acceleration, in meters per second per second, and the time, in minutes, during which the train travels at its maximum speed.arrow_forwardacceleration ++++ time (a) (b) (c) Fig. 3.10 Graphs describing a body moving with constant positive acceleration: (a) acceleration versus time, (b) velocity versus time, and (c) position versus time speed (m/s) What Have I Learned So Far?
