At t = 0, one toy car is set rolling on a straight track with initial position 17.0 cm, initial velocity -4.1 cm/s, and constant acceleration 2.90 cm/s2. At the same moment, another toy car is set rolling on an adjacent track with initial position 9.0 cm, initial velocity 6.00 cm/s, and constant zero acceleration. (a) At what time, if any, do the two cars have equal speeds? (b) What are their speeds at that time? (c) At what time(s),...
12-10. Car A starts from rest at t-0 and travels along a straight road with a constant acceleration of 3 m/s until it reaches a speed of 27 m/s. Afterwards it maintains this speed. Also, when-0, car B located 2000 m down the road is traveling towards A at a constant speed of 20 m/s. Determine the distance travelled by car A when they pass each other. 20 m/s 2000 m 12-11. A particle travels along a straight line with...
need help with ANALYZE PART A AND B and FINALIZE EXPLORE A car is moving with constant acceleration along a straight road (A) Determine how the velocity and the displacement of the car vary with time if the car is initialy moving to the right with a speed of 9.0 m/s and has an acceleration to the right of 1.7 m/s (B) Determine the velocity as a function of time when the velocity is instead initially to the right and...
Two cars drive on a straight highway. At time t=0, car 1 passes mile marker 0 traveling due east with a speed of 20.0 m/s . At the same time, car 2 is 1.1 km east of mile marker 0 traveling at 28.0 m/s due west. Car 1 is speeding up with an acceleration of magnitude 0.30 m/s2 , and car 2 is slowing down with an acceleration of magnitude 0.40 m/s2. At what time do the cars pass next...
