X = x o + v o ( t – t o ) + ½ a ( t – t o ) 2
Since here we have two uniformly varied movements, and each AM is described by two equations: Now we ask ourselves ¿How many equations describe this problem? Exactly four. Find:Ī) How much time did the car take to get at the truckī)Initially, what was the distance between themĬ) The speed of each vehicle when they are alongĭ) The position and speed graphs vs time, for both of themįirst of all, as usual, we start with the sketch.Īsí eran los esquemas de No Me Salen cujando los hacía a manopla. Both of them are moving with constant acceleration, 1,8 m/s ² for the car and 1,2 m/s ²for the truck, and they cross over when the car is at 45 meters from its departure spot. KINEMATICS, Uniformly Accelerated Motion Ex 13, EXERCISES OF PHYSICS onlineģ.43 - A car and a truck start simultaneously, from rest, with the car at some distance behind the truck.
