A car is stopped at a traffic light. It then travels along a straight road so that its distance from the light is given by x(t) = bt^2 - ct^3, where b = 2.20 m/s^2 and c = 0.130 m/s^3. Calculate the average velocity of the car for the time interval t = 0 to t = 12.0 s.

A car is moving along a straight road. At time t seconds, the position of the car (in feet) is s(t) = 51. Find the average velocity of the car over the time intervals given below. (a) t = 11 to t= 11.1 seconds (b) t = 11 tot = 11.01 seconds (c) t = 11 to t = 11.001 seconds (a) The average velocity of the car over the time interval from t =...

"Time headway" in traffic flow is the elapsed time between the time that one car finishes passing a fixed point and the instant that the next car begins to pass that point. Let X = the time headway for two randomly chosen consecutive cars on a freeway during a period of heavy flow (sec). Suppose that in a particular traffic environment, the distribution of time headway has the following form. k. X > 1 f(x) = 6 10 X51 (a)...

A car, C, and a truck, T are each travelling around the same horizontal circular track at constant speed. At the instant shown C is moving case. at 23.0 m s^-1 and T is moving north-west (i.e N 45 degree W) at 14.0 ms^-1. Draw a labelled vector diagram that shows the relation between the velocities of C and T and the velocity of C relative to T. Calculate the velocity of the car C relative to the truck T....

Practice Problems 12-12. Determine the total time required for a car to travel 1km along a straight road if it starts from rest (position 1), reaches a maximum speed at some intermediate point (position 2) and then stops at the end of the road (position 3). The car accelerates at 1.5m/s2 and decelerates at 2m/s. Hint: Draw a straight line with three positions marked on it. Write kinematics equations corresponding to positions 1-2 and 2-3, and solve the resulting equations...

A hockey puck is sliding on the smooth ice surface of a skating
rink as shown in the figure above.
The figure shows the puck’s position on the ice surface at a
sequence of equally spaced times t0, t1,
t2, t3 and t4. The x axis
shown is parallel to the rink’s length and the y axis to
its width. The marks along the axes are spaced 1 meter apart as are
the successive positions of the puck. The unseen...
