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...
A car starts from rest and moves along a straight line with an acceleration of a =10x(-1/5) m/s where x is in meters. Determine the cars position and velocity when = 4.481 s. X(4.481) V(4.481) =
A helicopter starts from rest at point A and travels along the straight-line path with a constant acceleration a. If the speed v = 33 m/s when the altitude of the helicopter is h = 44 m, determine the values of r, i, o, and as measured by the tracking device at O. At this instant, 0 = 38°, and the distance d = 159 m. Neglect the small height of the tracking device above the ground. ih А d...
A train starts from rest and starts with constant acceleration a = 3.6 m/s2 for 28 s. The train then coasts at constant velocity for 118 s. The train then comes to rest in 14 s. Please find the total distance covered by the train during the 160 s described. Kinematic equations: V = vo + at, x = x + vot + at", v = vi + 2aAx, x = x, + (v + v.)t.
Problem 5: The greatest possible acceleration or deceleration that a train may have is a and its maximum speed is v. Find the minimum time in which the train can get from one station to the next if the total distance between the stations is s. Assume the train starts from the first station at rest and stops when it reaches the next station.
