From the intersection of the two curves, read the time at which the trooper overtakes the car. For a better experience, please enable JavaScript in your browser before proceeding. She drives for 5 min at 12.5 m/s, 34 min at 33.0 m/s, 48 min at 15.5 m/s, and she spends 7.0 min eating lunch and buying gas. What is the velocity of the first car after th. We can speak of constant velocity, meaning that the rate of coverage of distance is constant with time. What is the rate of the faster truck? From time t = 12 s, the velocity of each car remains constant at its value at t = 12 s. Determine the time t at which car Q passes car P. t = . s. min (b) How far must the faster car travel before it has a 15-min lead on the slower car? An observer on a spacecraft moving at 0.700 \ c relative to the earth finds that a car takes 40.0 \ min to make a trip. After how many seconds will the first train. (b) How long does it take to reach that speed? At a certain instant, when the distance AB is equal to AC, both being 1 km, B decides to overtake A before C does. a. \frac{5d}{3300}&=\frac 14 \\ (a) Plot a graph of the cars position versus time. At that moment, the distance, A car weighing 2000 pounds and moving 20 miles per hour collides with a moving truck weighing 5000 pounds and moving two miles per hour. (b) Assuming the acceleration is constant, find the distance the plane moves. Passing lanes [ edit] Then it goes at 70 mph for five hours. Assume the cars start at the same point and arrive at the same destination which is 10.0 miles away. \displaystyle t_s = \frac{d}{55} Before reaching the curve of the exit ramp, the vehicle slows to 50 km/hr.
